Narrow Search Results (don't cover sidebar)

[jcuenod]

There is a user reports request to show morph stuff for search results.
It seems like a good idea to just shove search results into the space that the text occupies.

Best way of doing that and not potentially having weird overlap problems is:
When search results are visible, fade the chapter text and make user-select:none. Then put search results over chapter text.

If that doesn't work, we could try saving scroll position and then restoring after search results are hidden again.
