Drag to highlight a word on Safari after window snapping, will restore old window size like if window is dragged away

Describe the bug
Windows snapping on BTT correctly resizes a Safari when I snap, however, when I use my trackpad to highlight some words on Safari, the window will immediately resize back to the original size (like if window is dragged away). The workaround for me now is to disable "Restore old window size if window is dragged away". This happens also on Apple Mail.

The problem doesn't occur on Chrome when I highlighted a word.

The problem also occurs on a very old version of BTT when I was still using the old license.

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