"Maximize Window" does not work with iCalendar

Describe the bug
A clear and concise description of what the bug is.

The "Maximize" shortcut (as well as Maximize Window Right/Left) does not work with the default macos Calendar app.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):

If applicable, add screenshots to help explain your problem. (You can just paste or drag them here)

Device information:

  • Type of Mac: MBP 15" 2016
  • macOS version: 10.14
  • BetterTouchTool version: 2.717

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):
Open up calendar and resize it to not full screen. Map any action to "Maximize Window". I use "Three finger swipe up".

Attempt to invoke that action. It works for any window except for the calendar one.

Note: Before bug reporting, please make sure you have the latest version of BetterTouchTool and that you have already tried to restart your system :-). If you encounter a crash, please attach a crash log from the macOS Console.app from the "User Diagnostic Reports" section.

Hi, if you still have the problem, can you try using the shortcut when the mouse is on the window title, rather than inside the window? That seems to work for some apps (in my case Preview, I think); it's still strange behaviour.

there have been some improvements in the latest alpha version (> 3.840), maybe that helps in your case
