Only Turkish upper i-dotted (İ) key doesn't work and triggering Home key event

Tested on two different arch based Linux/GNU distros.
Qt 6.2.3 online installation and up to date.

All letters tr_upper = "ABCÇDEFGĞHIİJKLMNOÖPRSŞTUÜVYZ";
All letters tr_lower = "abcçdefgğhıijklmnoöprsştuüvyz";

Turkish upper case characters ÇÇĞĞÖÖŞŞÜÜ these are normal but only upper i-dotted char (İ) is problem

I think Capital i-dotless (I) is conflicting with Capital i-dotted (İ) or only Capital i-dotted (İ) is problematic. There is no any input conflict on QTextEdit kind widgets and Qt6 accepts typing upper i-dotted (İ) but when open a virtual keyboard looks like attached screenshot besides Qt6 and scintilla integration has keysequence/keybinding conflict with upper i-dotted(İ). When i click Caps Lock and i (İ) triggering "Home" key event. EventListener shows unstable keycode and keysequence matches. Lowercase i-dotted is ok, but upper case i-dotted does not match the right keycode/keysequence like g-breve/G-breve match.

Onboard keyboard screenshot was added to show how it should be.
Qt5 side is Ok, Compiled application works as expected with upper i-dotted (İ) key.
