Honestly, I think a case can be made that Ezra gave Sabine an assist in that scene. She probably had some force push, but Ezra did the bulk of the "force jump".
it's more that we first meet Sabine in a jedi wheelchair with Huyang declaring "she will never ever ever ever walk"
then we see her take her first faltering steps out of the wheelchair
and 5 minutes later she's beating Jesse Owens
i am sure the writers room and many many many discussion about this - they obviously chose a force power that we've seldom seen and that Sabine has no reason to be able to wield. they were very specific about how limited (or non-existent) her abilities are/were - SOMETHING has to account for this quantum leap
