Some SVG files do not start with `<svg`, but with `<?xml` and could include some additional metadata (e.g. a generator comment or licence header ...) Signed-off-by: Jyrki Gadinger <nilsding@nilsding.org>
this may cause an infinite re-request loop if the layout does not match Signed-off-by: Jyrki Gadinger <nilsding@nilsding.org>

Some app icon SVGs do not start with
<svgbut with e.g.<?xmland could include some additional metadata (e.g. a generator comment or licence header ...) before the expected<svgtag ... therefore let's check whether the reply is an SVG by peeking at the content-type header and the first 512 bytes of the response if the header was not enough.Resolves #9685, resolves #9689, resolves #9681.
fix confirmed on Windows 11 and on Linux (with
QT_QPA_PLATFORMTHEME=gtk3as the KDE Plasma one did not run into that)
