See how the bug crops icons on the left

SUMMARY
***
Konsole crops wide non mono icon-fonts in some circumstances
***


STEPS TO REPRODUCE
1. install nvim-0.9
2. install nvchad https://nvchad.com/docs/quickstart/install, but probably just installing nvim-tree is enough

OBSERVED RESULT
The icons are cropped in nvim-tree (but also elsewhere in the "ui" are cropped (see screenshot, on the left)

EXPECTED RESULT
The icons shall display like they do when they are "copy pasted" into a vim buffer (see screenshot, on the right)

SOFTWARE/OS VERSIONS
Linux: Kubuntu 22.04/Plasma 
KDE Plasma Version: 5.24.7
KDE Frameworks Version: 5.98.0
Qt Version: 5.15.3

ADDITIONAL INFORMATION
Other terminals e.g. sakura, st https://github.com/siduck/st, don't have this problem
I though color could be the issue, but the behavior is not reproducted by:
printf "\e[1;33m test \xE2\x9C\x94 󰉋  missing \e[0m test \xE2\x9C\x94 󰉋 missing\n"

The screenshot is using the following config:
<󰉋> 983627, Hex 000f024b, Octal 3601113
The used font is: https://github.com/ryanoasis/nerd-fonts/releases/download/v3.0.1/Meslo.zip

Bug reproduced with printf

No problem when next char is same color:
printf "\e[1;33m test \xE2\x9C\x94 󰉋 \e[0m test \xE2\x9C\x94 󰉋 missing\n"
Problem reproduced:
printf "\e[1;33m test \xE2\x9C\x94 󰉋\e[0m test \xE2\x9C\x94 󰉋 missing\n"
