Support BorderStyle = 3

[janparadowski]

Currently, this does not seem to be supported. Should make a (black) rectangular background to the subtitles/captions.

please?

The non-SVG render path could use https://developer.mozilla.org/en-US/docs/Web/CSS/box-shadow with everything 0 and spread > 0 to generate shadows of uniform spread thickness. Different outline width and height will require multiple shadows of the smaller dimension tiled along the longer dimension.

(box-shadow doesn't generate shadows around the element itself, so would need to use background-color for that part.)

The SVG render path could use BackgroundAlpha and deform it similar to how it does regular outlines.

You're asking a question in a completely unrelated issue because...?
