modernizr.min.js is causing unnecessary reloads of a page causing flashing of the browser window during page load (most noticiable with firefox). This empty script effectively wipes out the modernizr.min.js unnecessarily loaded by the Sphinx rtd theme (see readthedocs/sphinx_rtd_theme#724) Signed-off-by: David B.

Problem
When I go to any page using the RTD theme, my browser noticeably flashes white for a few dozen milliseconds before the page shows up. When I comment out
modernizr.min.jsfrom my HTML pages, the white flashes go away.Reproducible Project
I see this in every project that uses the RTD theme. Which means I can repro it here too: https://sphinx-rtd-theme.readthedocs.io/en/stable
Steps to repro:
Go to https://sphinx-rtd-theme.readthedocs.io/en/stable
(This already repros the bug, but it's not so easy to notice on first load. So let's go to step 2)
Click on "Configuration" on the left sidebar.
Expected: the Configuration page seamlessly loads
Actual: the screen flashes white and then the Configuration page loads
You can repro this 100% of the time by clicking on top level links on the sidebar.
Error Logs/Results
