Wikimedia Bugzilla is closed!

let's say the first parameter of {{sometemplate}} is supposed to be a url:

{{sometemplate|https://bugzilla.wikimedia.org/enter_bug.cgi?product=MediaWiki}}

rather than using the complete url as parameter {{{1}}} the template interprets this as parameter
{{{https://bugzilla.wikimedia.org/enter_bug.cgi?product}}} with value "MediaWiki".

How hard would it be to avoid this result by ignoring equals signs which are part of a URL (when identifying named and numbered parameters)...
