Video Editing - show video file original Frames amount

Something Changed in version 3.3.1 LTS Usualy it wasn't important what framerate the source is - in video editing timeline - it was plaiyng/showing every frame. But now it consider Strip time instead. Now, if you import a 25 fps video in 24fps project - it loses one frame every next 24 frames. And I don't know how long should Speed Control be scaled to match frames quantity.

Also an option to change source video framerate would Magicaly Help!
