New Nightly(AI-generated) UI tweaks in a leftside Options panel
https://reference.dashif.org/dash.js/nightly/samples/dash-if-reference-player/index.html

Left side panel of Playback has few options to wrap two lines, it creates a scrollbar but its just one option row hidden(atm) so not the best UI experience.

Options have a tooltip to give the extensive help text. Use compact texts such as this:

Reuse Existing SourceBuffers -> Reuse Existing Buffers or Reuse Existing SBs
Calc Seg Avail From Timeline -> Calc Avail From Timeline
MediaSource Inf Duration -> Use Infinity Duration
Reset SB on Incompat Track -> Reset SB if Incompatible
