Docs' index seems broken and crashes web tabs

Suggestion

When trying to use the docs for the crates at https://microsoft.github.io/windows-docs-rs/doc/windows/index.html I get a huge spike in memory use which some browsers can't (or choose not to) handle on Windows

• In Chrome I get an out-of-memory crash for a tab after it reaches ~2.5G of memory use (total browser use, not for 1 tab, though only 1 tab is opened), though the system isn't OOM.
• In Firefox the page continues to grow in memory use until ~4G (same, total browser use), then stabilizes.

I think simply focusing the search box triggers this huge growth, no need to even input any search string. Does it generate the full search index locally in a very inefficient way or something?

May I suggest improving the efficiency of the docs page?

This is generated by rustdoc which is known to struggle with large crates, but is otherwise out of our control.

I'd suggest using https://microsoft.github.io/windows-rs/features/ to figure out which windows crate features you might need to enable but otherwise avoid the docs.

Alternatively, you can use the windows-bindgen crate to generate just the bindings you need.

Are you clicking All Items in the docs? If so, don't do that. 😄

No clicking, though that's actually a non-issue, that page loads fine with lower memory use, and it might be lazy-loaded(?) when you jump to the end, it loads more (but still, jumping all the way to the last item doesn't crash anything)

I think this is the main issue but there are probably others: rust-lang/rust#131156
