New gesture drawing glitch with Wacom pen

[SH4R1K7]

This was found as part of https://github.com/Robbendebiene/Gesturefy/issues/575

demo:

steps:

• draw a gesture a few times
• after 1 or <10 attempts input is no longer traced, a right-click menu pops up instead, and a duplicate trace appears below and outside the input area
• closing and opening the input panel, or a different gesture panel, has no effect - the issue is present immediately
• only closing the addon settings page/tab and reopening it clears the issue

It would be interesting if any errors get logged, can you please:

1. open Gesturefy settings page
2. press Ctrl + Shift + K to open the console
3. reproduce the issue
4. post any console logs here

Can you also please record the moment when the duplicated trace appears? This seems to be the only thing that's missing in the recording.

Hi, sorry for the long wait, here's how to trigger it - nothing special - but the error log is pretty clear why it locks up.

Not sure why the duplicate ghost trace doesn't appear sometimes though, couldn't get it to happen.

Here's the trace for setPointerCapture:
