Details & Reproduction Steps

1. When setting A-B loop during pause state, the indicator would not rerender immediately unless perform any actions afterwards which force the OSC to rerender.

2. If ab-loop-b point is set before the ab-loop-a point, the loop is supposed to work normally from ab-loop-b to ab-loop-a. But the indicator refuses to draw the range in this circumstance.

I carefully read all instructions and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
