Region: NA
Type of Bug: Keybind
Description: Sometimes, Mouse4 (the forward thumb button called "Thumb Mouse button 2" in-game) or spacebar stop working in-game. Mouse4 is bound to "Equip Secondary Weapon" (pistol) and spacebar is bound to Jump. I've only observed this with these two buttons. I believe it started in 6.0 and happens in 6.1, but I don't think I ever experienced it prior to 6.0.
In that window of time when the key is not working, I go to settings and bind Mouse4 to anything but it doesn't do anything; it seems that the game entirely ignores the Mouse4 input. I can bind something else to "Equip Secondary Weapon" and successfully switch to my pistol. The Mouse4 and spacebar buttons themselves always work fine in other programs.
It does not depend on which exact weapon I have, or even whether or not I have a primary weapon at all. Alt-Tab does not fix it (there's a chat box issue that is fixed with Alt-tab). Dropping my gun does not fix it.

Steps to Reproduce: Start a game. (a) Press spacebar or (b) Equip primary gun or knife and press Mouse4.
Expected Result: (a) Jump action, (b) equip pistol.
Observed Result: Nothing happens.
Reproduction Rate: (a) rarely, lasting a few seconds once every couple of games. (b) very often, lasting between a few seconds and a few minutes several times per game. The issue comes and goes seemingly randomly. They can happen together.
