Search does not terminate for terms that are not found.

Problem

Searching for a string in the docs using the search bar does not terminate ( result is stuck on Searching ... ) when the string is not found.

Reproducible Project

This can be reproduced on: https://sphinx-rtd-theme.readthedocs.io/en/latest/ by searching some random string that isn't present.
But has also been observed on: https://arbor.readthedocs.io/en/latest/ which uses this theme.

Expected Results:

This message to be displayed instead (or something similar):
Your search did not match any documents. Please make sure that all words are spelled correctly and that you've selected enough categories.

Environment Info

• Python Version: Python3.7
• Sphinx Version: v3.4.3
• RTD Theme Version: v0.5.1 (as well as master)

This seems related to the sphinx change #1021, maybe something with our extension and not with the theme.

I think I know were the problem is, this is because we install by default an old version of the theme, you should pin your version to 0.5.1 (this is fixed there). For our docs we need to install it with pip

This was fixed with 24f8e31, note the theme currently is using an old version of the theme so that's why our search is bugged
