Full-Screen Flash is throttled, even if Throttle expensive background timers

Reported by jasper.r...@gmail.com, Sep 29

Issue description

Chrome Version: 69.0.3497.95 (Official Build) (32-bit)
Chrome OS Version: 10895.56.0 (Official Build) stable-channel daisy
Chrome OS Platform: Samsung XE303C12
<b>Network info: <network, encryption type, router model (if known)></b>

Please specify Cr-* of the system to which this bug/feature applies (add
the label below).

Steps To Reproduce:
(1) Disable Chrome flag "Throttle expensive background timers"
(2) Run a flash video in Chrome and switch to full screen (I am watching flash videos on UFC Fight Pass at www.ufc.tv behind paywall)
(3) After a few seconds Chrome console reports "Active resource loading counts reached to a per-frame limit while the tab is in background. Network requests will be delayed until a previous loading finishes, or the tab is foregrounded. See <URL> for more details", followed by "resource request failed." and "http error: request resource failed." Then video freezes.

Expected Result: Full screen Flash video should not be deemed a background tab, so not be throttled in the first place. But even then, when the flag is Deactivated, nothing should ever be throttled.

Actual Result: Full screen flash is throttled and freezes. Console reports that throttling is done per message quoted above.

How frequently does this problem reproduce? Always

What is the impact to the user, and is there a workaround? If so, what is
it? Cannot watch full screen flash. No known workaround.

Please provide any additional information below. Attach a screen shot or
log if possible.

Issue Title should read:
"Full-Screen Flash is throttled, even if 'Throttle expensive background timers' is Deactivated"
I also now tested playing the same video in not-full-screen while "Throttle expensive background timers" flag is Deactivated, then switched to another tab while playing. Playback of the now background tab stopped a few seconds later and console confirmed again "Active resource loading counts reached to a per-frame limit while the tab is in background. Network requests will be delayed until a previous loading finishes, or the tab is foregrounded. See https://www.chromestatus.com/feature/5527160148197376 for more details"
-- It's as if setting the feature flag to Deactivated never takes any effect and the feature cannot be turned off.
My Chromebook updated itself and I cannot replicate this issue anymore on these versions:
Google Chrome	69.0.3497.120 (Official Build) (32-bit)
Platform	10895.78.0 (Official Build) stable-channel daisy
Flash (not sure if this updated): Flash	31.0.0.108 /opt/google/chrome/pepper/libpepflashplayer.so

The error message does not appear anymore in the console and the same video flash files that consistently led to this problem now play fine in full screen mode.
Status: WontFix (was: Unconfirmed)
Closing as per #3
