I'm attempting to replace the a Google Fonts stylesheet URL with the contents of the stylesheet. I was using HTMLRewriter about a week ago and it was working fine, but I noticed today after I published to my worker, that it stopped working as expected even though it I had not made any changes that would have made a difference.

So, I started testing out different selectors. This seems to work fine:

rewriter.on(`link[href*="fonts.googleapis.com/css"]`, ...)

But, when a colon was added to the font, it wouldn't work, and the handler would not be called:

rewriter.on(`link[href*=":fonts.googleapis.com/css"]`, ...)

I was having issues with these two cases as well. This works fine:

rewriter.on(`[href*="fonts.googleapis.com/css?family"]`, ...)

But, this does not:

rewriter.on(`[href*=fonts.googleapis.com/css?family=Lato"]`, ...)

It feels like the last two cases could be an issue with the equals sign.
