[bug] Can't sneak-click or right click

[dzervas]

Version
MC 1.20.1 MW 1.13.0

Describe the bug
When the mod is enabled I can't shift or ctrl click or right click. That means that sneak placing or braking blocks no longer works.

Note that I'm talking about non-GUI state, when you play normally (no open menus/whatever)

To Reproduce

1. Sneak-place a block
2. Sneak-break a block
3. Shift (sprint) place/break a block
4. Nothing happens

Expected behavior
For the block to get placed/broken

Log
I had the console open and I saw nothing of interest.

Additional context
When I change sneak to be "Toggle" and not "Hold" I can place/break blocks normally, so I imagine something's wrong with the way sneak triggers?

Also I tried to un-map any bindings that where bound to Ctrl or Shift. nothing changed.

The moment I disabled the mod everything worked as expected, that's why I think it's MW's bug
