Description Kueno 2023-09-07 19:47:41 PDT

The spec that VTTRegion::setScroll throws a SyntaxError in dead code has been removed at https://github.com/w3c/webvtt/pull/28, and now it should ignore assignment of an invalid string.

WebKit is failing the corresponding WPT: https://wpt.fyi/results/webvtt/api/VTTRegion/scroll.html?label=experimental&label=master&aligned&q=webvtt
