Rollup merge of #113100 - GuillaumeGomez:search-result-long-name, r=notriddle

Fix display of long items in search results

Fixes #113060.

You can test the result [here](https://rustdoc.crud.net/imperio/search-result-long-name/lib2/index.html).

To make it a bit better, I also reduced a bit the size of the short documentation from half to 2 fifth of the width.
