Steps to reproduce the problem:
1. Create a webpage with > 10 html5 video tags (happens w/ longer vidoes mostly)
2. Set up some JS code to autoplay clips when visible

What is the expected behavior?
dynamic content should load when requested, and the user should be able to browse away from the page at any time

What went wrong?
The large number of clips blocks dynamic content from being loaded, and dramatically delays any link clicked by the user - sometimes for > 1 minute.

Did this work before? N/A 

Does this work in other browsers? N/A

There was a previous bug reported with this problem here, marked as fixed: https://bugs.chromium.org/p/chromium/issues/detail?id=234779

However, the problem persists, even if I don't see 'pending' resources in the network panel.  I've tried setting preload="none" without relief of problem, as well as using alloyk's solution without resolution.  

Page works perfectly on Safari.
