Hi! Thanks for this lib. I'm using it pretty extensively.

I nailed down exactly the situations where this bug occurs, and when it doesn't.
An example for the bug: Given hotkey: 'ctrl+l', sending 'alt' in the callback fn will send ctrl+alt+l, even if 'ctrl+l' was physically released, trigger_on_release is set to True, as so is suppress.

I checked that via is_pressed.

1. In the the attached file there are 3 main functions (0,1,2) and 4 groups (A,B,C,D) that check those functions from different angles.
2. The functions print whether ctrl is_pressed, with different minor changes between them.
3. The groups add elements like calling the functions in a different thread, sleeping or releasing the hotkey etc.
4. The lines are commented because multiple ones are binding the same hotkey, so please uncomment them as needed.
5. The summary of each group is written inside a tri-quote above it.

Results:

• I tested on the PyPi lib, the master github branch and the suppress branch.
• The master branch and the suppress branch give identical results, so let's refer to them as the repo from now on.
• To bypass the bug, PyPi needs a different thread (call_later), and: either some sleep before checking is_pressed, or a manual keyboard.release. Both are sufficient.
• The repo needs a call_later and a sleep ONLY. Manually releasing doesn't have any effect.

Hopefully that sheds some light on the issue!

Thanks again,
