Summary says it all. The first Super+space just inserts a space and no input
engine selector popped up. Super key needs to keep pressed though, the 2nd
Super+space pops up the selector as expected.

Reproducible: Always

1.Install from Fedora-Cinnamon-Live-x86_64-39-20230920.n.0.iso with ja
2.Boot and open gnome-terminal and/or xed
3.Press Super and space
4.Release space key only and press space key again
Actual Results:  
space character are inserted at 3, and the selector popped up at 4

Expected Results:  
the selector should be popped up at 3 without inserting space
