PressedKeys not properly clearing key on shift combinations

[reinhard-sanz]

Describe the bug

In some cases when pressing shift and trying to add any special chars ($,&,%,() etc.) they are sometims not properly removed from the pressedKeys array.

Reproduction

svelte.dev/playground/6ac44aba47cf45a7a15654f918770d4b?version=5.22.5

It does not happen all the time and is a bit difficult to reproduce so you are gonna have to try a fews time to get the bug to show up, but it easiest if you press "shift" and then just hammer down the the special chars on your keyboard :)
But it definetely shows up.
(Same goes for "chars" that require a special combination to show up)

Update, you can reliably replicate this like this:

1. Pressing and holding "Shift"
2. Pressing and holding any special character e.g. "&"
3. Letting go of "Shift"
4. Letting go of the special char
