It's not possible to rename any node while using wayland session under my linux distro. Using Godot 4 beta15. Tried changing keyboard layout and same result. If I swith to X11 session then it works. Also beta14 doesn't have this problem with wayland session.

### Steps to reproduce

Literally try to rename any node under wayland session with beta15

### Minimal reproduction project

n/a
if (!keysym.is_empty()) {
					k->set_key_label(fix_key_label(keysym[0], keycode));
				} else {
					k->set_key_label(keycode);
				}
				if (keypress) {
					k->set_unicode(fix_unicode(tmp[i]));
				}
				k->set_echo(false);
				if (k->get_keycode() == Key::BACKTAB) {
					
					k->set_keycode(Key::TAB);
					k->set_physical_keycode(Key::TAB);
					k->set_shift_pressed(true);
				}
				Input::get_singleton()->parse_input_event(k);

			return;

		memfree(utf8string);
#else
		do {
			int mnbytes = XmbLookupString(xic, xkeyevent, xmbstring, xmblen - 1, &keysym_unicode, &status);
			xmbstring[mnbytes] = '\0';
			if (status == XBufferOverflow) {
				xmblen = mnbytes + 1;
				xmbstring = (char *)memrealloc(xmbstring, xmblen);
			}
		} while (status == XBufferOverflow);
