PhpStorm weird windows in switcher

[ibrahimabdo]

Describe the bug
After the last update of AltTab, I am starting to get weird windows in switcher when I press Alt + Tab while using PhpStorm 2020.3.

I think it could be related to #652

Hi @ibrahimabdo! I see that you are using the EAP. The EAP indeed has some unique problems that the stable release doesn't. You mentioned #652. In that ticket I did a change so that AltTab ignores one of the accessibility notification from EAP products from Jetbrains. This notification is used to detect if a window becomes tabbed into another window. Jetbrains products don't use native AppKit tabs in the first place, so it's safe to not get this notification.

What I'm saying is, yes it is related to #652 because this ticket was also about an issue in an EAP product. However, the issue is quite different, and I don't think the recent code change can be responsible for new windows appearing.

I think the issue you're facing is exactly the same as #562 so I will close this ticket as a duplicate. Maybe you could ask @mfn if they are seeing the issue these days. Last time we discussed it, they said the issue is gone now, but you seem to be facing it still.

Another thing to consider is the broader story of #456. I'm still looking for someone to help me devise a better heuristic to avoid showing things that are not windows.

After #652 was fixed, I did not notice further or other anomalies but yes, #562 sometimes occurs for me, but very rarely. And also did before the EAP and I saw it once since the EAP.
