Holding down F3 and pressing an either default or modified keybind and releasing the F3 key brings up the F3 debug screen which is not vanilla behaviour.

Example: Pressing F3, holding it down, pressing G, releasing G and afterwards releasing F3 brings up the F3 Debug menu while it is expected for the F3 debug menu not to show up when using a debug function.

The issue appears with a modified keybind as well.

Tested with latest DebugKeybind Fabric release v1.1.0 on a Vanilla instance
