My modified 'aurorae.qml' that causes the issue

I've been modifying the 'aurorae.qml' file to create a custom decoration. It seems that using 'Text.Raised' as text style causes instant crash when the title has an emoji.

STEPS TO REPRODUCE
1. Edit the 'aurorae.qml' file (either in '/usr/share/kwin/aurorae/' or ~/.local/kwin/aurorae)
2. Change the line 148 to 'textFormat: Text.StyledText'
3. Add this line bellow the previous line: 'style: Text.Raised'
4. Save the file
5. Restart kwin
6. Navigate with a browser to a page that has an emoji in its title (eg. https://www.youtube.com/watch?v=r8tBn3c2BK0)

OBSERVED RESULT
kwin continuously crashes/restarts until the tab is closed.

EXPECTED RESULT
No crash

KDE Plasma Version: 5.21.5

ADDITIONAL INFORMATION

That's why I deliberately set it to plainText. 
Crash is upstream in Qt and reported.
