BUG: CSS strings truncated at ":"

[invalidarg]

Fixes issue #59623

Changes maybe_convert_css_to_tuples called by style.map() so that it no longer truncates the CSS-value at the ":".

e.g. background-image: url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" id="flag-icons-dk" viewBox="0 0 640 480"><path fill="%23c8102e" d="M0 0h640.1v480H0z"/><path fill="%23fff" d="M205.7 0h68.6v480h-68.6z"/><path fill="%23fff" d="M0 205.7h640.1v68.6H0z"/></svg>'); will no longer be truncated to the tuple ("background-image" , "url('data:")

needs a unit test to demonstrate it solves the test

@attack68 the failing test seems unralated to my change? I'm not sure how to proceed.

The pre-commit.ci is failing but I'm not sure how to fix. I think it fails due to this string.

msg = (
	"Styles supplied as string must follow CSS rule formats, "
	"for example 'attr: val;'. 'err' was given."
)

ruff format failed. This means you need to install ruff and run ruff format in terminal on your file. It will edit it according to specifications, i.e. it might remove some whitespace or dangling commas etc.

Thanks. It looks good now I think :)

Thanks. LGTM.
This is a nice fix for the issue, although we acknowledge we can't go further without a proper CSS parser.
