Expected Behavior

The replay buffer to start

Current Behavior

The replay buffer sometimes doesn't start, but the button becomes filled with blue as if it has started (Despite the text remaining the same) which is misleading and has lead to me missing many potential clips the past year.

Steps to Reproduce

1. Do something potentially requiring a save of the Replay Bufrfer
2. "Flush" the Replay Buffer by toggling it off and on again to trim the beginning of a potential clip.
3. Sometimes clicking the Replay Buffer will cause it to change it background color to blue, indicating the buffer has started. Sometimes, it actually still says "Start Replay Buffer" and has not actually toggled the feature on.

This leads to many lost potential clips.

Start with the linked OBS log and reproduce the replay-buffer toggle sequence described in the issue, comparing the button's highlighted state with whether the buffer actually starts. Trace the replay-buffer toggle flow and its UI state updates; done means repeated toggling keeps the label, highlight, and running state consistent.
