Switching gamemode with F3 + F4 applies F4 keybind

If F4 is bound to an action, using the F3 + F4 shortcut to change gamemodes will apply the F4 keybind as well, whereas in previous versions this did not happen.

Steps to reproduce:

1. Set a certain keybind to F4 (most noticeable with toggle perspective, dropping item, or cinematic camera)

2. Run the F3 + F4 gamemode switcher

3. Run this in both the latest full release (26.1.2) and latest pre-release (26.2 pre3)

Expected outcome: There should be no difference between the versions

Actual outcome: In the latest pre-release, the key bound to F4 is applied after you let go of the F4 key to run the F3 + F4 shortcut, when in the latest full release this did not happen
