There’s an inconsistent theme for the highlighting of link and script tags in the Inspector.
Some tags are completely grey and not highlighted with the normal colors for html elements. It occurs frequently to script and link tags at the bottom of html documents. It also seems to be pretty common for noscript tags also.
I presume it’s a deliberate design choice to grey out the elements that aren’t so important. But it would be nice if there was an option to highlight script tags like normal element tags.
