(X11) New application window doesn't appear on a dock

Sometimes programs launch new windows and destroy old ones. Those new windows may not appear on dock until you launch some new windows, reload shell etc.

I can give a reproducible example with LibreOffice (7.3.x, 7.4.x).
Tested on Ubuntu 22.04 with both "Ubuntu Dock" and "Dash to Dock" v75

Steps to reproduce
1) Create simple CSV file with content
"entity_id","type_id"
2) Open it with LibreOffice Calc
3) On "Text Import" dialog press "OK"
4) "Text import" window closes, new LibreOffice window appears
5) LibreOffice Calc icon is missing until you enter "Dash to Dock Settings", reload shell etc

I wasn't able to reproduce this issue on a Wayland session and with the original dash

Video demonstration attached bellow
