When dragging window with cursor after shortcut to maximize window, it reverts back to previous window size

This has been ongoing for many many months. I believe it started with MacOS 15, but not 100% sure. When using a shortcut in BTT to maximum window to left half (or right half, 1/3, etc.) the shortcut works correctly, but if I then go to drag the window to another space, it resizes to the original size it was before using the shortcut. This never happened (been using BTT for years) until several months ago and I assumed it was a MacOS change, but I just used Magnet instead and noticed it doesn't do that with that app. Here is a link of a 12 second video of the behavior.

Can anyone replicate this?
