silverwind 57a0a7ef64 Fix opaque background on mermaid diagrams (#21642) ... Browsers introduce a opaque background on iframes if the iframe element's color-scheme does not match the document's color scheme which in case of a dark theme results in a mismatch and the browser adds a white background. Avoid this by specifying the same color scheme outside and inside the iframe. See https://fvsch.com/transparent-iframes for more info. My initial attempt was to make the iframe document the same color-scheme as the parent page (light or dark) but with that, there was a ugly background flash on load in Chrome because Chrome apparently always loads iframe in light scheme initially. Firefox still shows a background flash on load but this is not possible to get rid of and it's certainly a browser bug.
