The incorrect rendering of mc using Konsole 18.12.0

After upgrading to Konsole 18.12.0, I noticed that window borders in Midnight Commander were being rendered incorrectly. What I mean by that they are more squiggly instead of straight lines. Downgrading to 18.08.3 fixes the issue, so this seems like a regression introduced with the emoji support. To better explain what I mean I've attached screenshots of how it looked like in 18.08 and how it looks now.

Though it shouldn't matter, the font I use is DejaVu Sans Mono. Midnight Commander is version 4.8.21 with Unicode support. The problem is present using other appearance presets in Konsole.

I've ruled out it being a problem with Midnight Commander, as it's still present after removing the mc config. For testing purposes I also ran mc with LC_ALL=C, but this didn't change the rendering.

Package versions used:

Konsole 18.12.0
Qt 5.11.3
Plasma 5.14.5
KDE Frameworks 5.53.0
