If I do it in gedit, and cut and paste "👦🏻" from there to writer it happens too, so its not any problem with the input method. Seems there really are two chars there, Unicode Character 'BOY' (U+1F466) followed by Unicode Character 'EMOJI MODIFIER FITZPATRICK TYPE-1-2' (U+1F3FB) so its on the render side of things
Comment 2 Caolan McNamara 2018-11-09 12:30:55 UTC 
If I erase all emoji fonts except for Symbola, then I get the same bustage in gedit as well as LibreOffice, so a key problem seems to be font selection
Comment 3 Caolan McNamara 2018-11-14 11:28:29 UTC 
The key font we want to use is a non-outline font so is rejected by LibreOffice as a candidate, so we'd have to relax that restriction and tweak things to bubble the font down to our cairo renderer. The good news is that if we can get it there, then it seems to render fine

implemented upstream as https://cgit.freedesktop.org/libreoffice/core/commit/?id=dcf7792da2aa2a1ef774a124f7b21f68fff0fd15

Comment 7 Bill Sanford 2019-12-12 13:32:39 UTC 
In the OP steps, I couldn't use CTRL-SHIFT-e, but I did use :<emoji name>: and as soon as I entered the second colon, I got the emoji and tried to reproduce the bug. I used writer 6.0.6.1-20 and it looks like it is fixed.
