rustdoc source view: hover gap in file picker

[jsha]

Steps to reproduce:

1. Visit https://doc.rust-lang.org/nightly/src/alloc/string.rs.html#2453
2. In the sidebar, hover mouse over "alloc". Note that mouse indicates a clickable item.
3. Slowly move the mouse leftwards towards the disclosure element (▶).
4. Note that at some point, the mouse hits a dead zone where it is no longer over a clickable item. When this happens, clicking does nothing.
5. If you continue moving the mouse leftwards, onto the disclosure element, it will indicate a clickable item again, and clicking it will open/close the folder.

Expected results:

The whole line, including the disclosure element and the folder name, should be clickable.

I can't reproduce this bug. It is using <details> now, not sure if it was merged before or after you opened this issue though. Can you double-check you still have it please?

[jsha]

This still reproduces for me. I forgot to mention: this is in Chrome on Linux.
