screenshot showing the issue

Description of problem:
Qt does not seem to be able to properly display JetBrains Mono, as installed from the repositories. When JetBrains Mono, Regular is selected, it appears to show the Bold style instead.

JetBrains Mono NL (same font minus ligatures, also as installed from the repositories) does not share this issue.

Version-Release number of selected component (if applicable):
5.15.2-30.fc35.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Install jetbrains-mono-fonts-all
2. Get a Qt application (for example, Konsole or KWrite) to display text using JetBrains Mono
3. Compare results with JetBrains Mono NL

Actual results:
It shows glyphs from the wrong font style (bold)

Expected results:
It should show glyphs from the correct font style (regular)

Additional info:
This started happening since https://src.fedoraproject.org/rpms/jetbrains-mono-fonts/pull-request/2 or https://koji.fedoraproject.org/koji/taskinfo?taskID=83085933, which switched the JetBrains Mono font to OpenType format, while keeping the JetBrains Mono NL font in the TrueType format.
This does not seem to happen in Gtk applications (like gedit)

This message is a reminder that Fedora Linux 35 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 35 on 2022-12-13.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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
'version' of '35'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 35 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 Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.
