Application Dashboard, when I type name of the app, it accepts only a few letters, like "mou"  (i wanted to type mouse), and stops accepting any more letters. I can use BACKSPACE, but I can't type anything more (even if the field is empty).
I have to close application dashboard (meta) and open it again (meta) and I can type again, however just a few letters. Sometimes I can type more, like "filelight"

I see some pattern here. When I type, dashboard is automatically filtered, if any apps exist, I can type, till they all disappear/ are filtered out because the input doesn't match - and this moment I can type 1-2 more letters - after none of them match and all input is blocked.

When I want to type "mouse", at "mo" there is only one app "mouse" visible, but when I add "u" (mou) more apps are visible ("device automount", cursors, accessibility,...) and at this moment Application Dashboard stops accepting any more letters. 
Looks like it's connected with filtering apps.

It happens on my other PC with the same configuration (Kubuntu 25.04, KDE 6.3.5)
