Steps to reproduce:
(1) Inject the bootstrap script into docs.google.com with an extension
(2) Load any Slides presentation
(2) Bootstrap script loads second script (slides_script.js) into the document 
(4) Wait 10s and click on "Presenter View" to trigger click handler

Expected result:
MR dialog appears to offer device selection

Actual result:
- start() is rejected with "start() requires user gesture"
- Script works if --disable-gesture-requirement-for-presentation is passed

This is in a click handler, it's not clear how the user gesture token is getting lost here, whether it is idiosyncratic to docs.google.com or if it is a bug.

Could try a narrower repro case with an html file.
