Ctrl-x in grub2 menu doesn't work on MacBook Air with EFI boot

Description of problem:
When booting on a MacBook Air (select the EFI boot, boot option) and editing the boot command line in grub's menu the Ctrl-x key press is not recognized so you can't boot further.
A workaround is to use F10 which is not mentioned.
The original bug mentions this fixed in grub2-2.02-0.2.4.el7 but maybe it is hardware dependant (or a regression).

The earliest version I could find is grub2-2.02-0.2.10.el7.x86_64.rpm from RHEL 7.0 and it has the same problem. At this point I think this is hardware dependent.
Filing here for Rawhide:
I'm also seeing the same thing on Rawhide with grub2-2.02-0.21.fc24.x86_64.rpm
Confirmed on a HP laptop. Model Folio 9470m
Ctrl-x and Ctrl-c on grub just type x or c.
(undocumented) F10 confirmed to work.
install image for fedora-21-x86_64, not really sure what's the version. it does not output it anywhere.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.
More information and reason for this action is here:
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
This is reported still to be the case in F27, at https://bugzilla.redhat.com/show_bug.cgi?id=1503496#c27 .
For the record, pjones mentioned on IRC that the message used to mention F10 as well as ctrl-x and it was actually specifically *removed* because other people using grub in a case where F10 doesn't work (serial console) got confused.
So the problem is, we have two possible 'I'm done' key combos, both of which work in *some* cases, neither of which works in *all* cases...
Note: also seen on mac mini 5.1 (mid-2011). I actually tried this with CentOS 7 but think it's better to report upstream. F10 seems to work on my mac keyboard.

For the record seen from this DVD image: CentOS-7-x86_64-DVD-1708.iso
'upstream' for this issue is grub, btw. Fedora isn't customizing anything here.
