Fix search.highlight feature when loading from file:// URL

I don't believe there is any easy way to hide the search highlighting, though, after navigating to a search result. Consequently, I didn't enable it by default for our docs.

I don't believe there is any easy way to hide the search highlighting, though, after navigating to a search result. Consequently, I didn't enable it by default for our docs.

This would actually matches my experience in other Sphinx themes. Typically I click the section permalink to disable search highlighting if it is too annoying (sadly this doesn't always work).

I was excited to see the feature could be disabled at build time for this theme though. However, since the selected text follows the light/dark scheme CSS, it's not a bad idea to enable the feature for our docs. For other light-only schemed themes, I tend to use the "dark reader" browser extension, which looks rather ugly when highlighting search results.

Not exactly related, but for the features that are solely implemented in JavaScript and therefore don't require a rebuild to enable, it could be neat to allow them to be interactively toggled in our docs in order to allow users to experiment with them.

I think some features are excluded from the HTML in the templates if not specifically enabled. We could easily use the task-list directive (+ custom JS in our docs) to implement the toggling.

Incidentally, I was contemplating something similar to the admonition icons because there are sample snippets that provide a complete suggestion for Octicons and FontAwesome.
