Extensions shouldn't have the autoplay policy applied to them. beccahughes@, can you PTAL?

I can replicate this on 69.0.3452.0. It looks like the flag for extensions is being cleared by mistake on a same document navigation.

[Autoplay] Do not clear flags on same document navigation

This fixes a bug where AutoplayFlags are cleared on same
document navigations. Flags are associated with a
Document so we should not do this.

Able to reproduce the issue on Windows 10, mac 10.13.3 and Ubuntu 17.10 using chrome reported version #67.0.3396.62 and latest canary #69.0.3451.0.
Removing the Needs-Bisect label as the fix has already landed in comment #9. Adding label RBS as it seems to be a recent regression. Please feel free to remove the same if not required.

Will verify the fix on as per test steps in C#4.

Thanks...!!

Able to reproduce the issue on Mac 10.13.3 using chrome build without fix.

Verified the fix on Mac 10.13.3, Win-10 and Ubuntu 17.10 using Chrome version #69.0.3452.0 as per the comment #4.
Attaching screen cast for reference.
Observed that video playback began and the autoplay policy did not apply to browser extensions.
Hence, the fix is working as expected. 
Adding the verified labels.

Thanks...!!
