RGBA color specification does not work in OS 3.3.10 / OSWeb 1.4
After the update to OpenSesame 3.3.10, I ran into an issue with OSWeb.
Until 3.3.9, I used rgba with an alpha of .01 to align text, as suggested in the manual (https://osdoc.cogsci.nl/3.3/manual/stimuli/text/)
However, this now produces an error:
uncaught exception: Invalid color specification: rgba(0,0,0,.01) (string) See the console for further details
A workaround is, of course, to use rgb and set the color to the backgroundcolor. But is there still a way to hide text using alpha? This could be useful for multicolored background.
Attached is also an example to recreate the error. Hiding text by setting the color to the background color works but setting rgba produces the error. This error occured for me with both firefox and edge (but only in the browsers, not when starting within OpenSesame, which is why I assume this error to lie with OSWeb).
