WebGL is sometimes blocked outright instead of put behind a click-to-play placeholder
In legacy/trac#21805 (moved) we put WebGL behind a placeholder with the help of NoScript. This works well e.g. for http://webglsamples.org/aquarium/aquarium.html. However other sites report just that WebGL is not supported and it therefore gets blocked outright:
Giorgio, you mentioned in comment:5:ticket:21805 that this worked correctly with NoScript 10.1.8.2. Is that a regression on NoScript's side or an issue with WebGL detection on the website?
