[TaterToes]

closes #30177

checks if currentTime is less then the time when autoplay starts, then ~~creates a new autoplay~~ slices frames on demand

i dont know where the code is to click on the progress bar to change the time so i would like some help on where that function is so i can add an event listener

seems like this approach doesnt work as the score stays the same within the replay timeline. might just have to scrap this pull request or figure out how to deal with that.

I don't understand what you're saying here? Can you explain?

This idea will work, but as per the linked issue, we might wanna approach this more holistically. Not sure how yet, though.

I've tidied up commit history slightly.

Closing as of now, might continue another pull request with a different solution in the future.
