Opacity transition does not start rendering for opacity target values < 1

Reported by tszynal...@antimoon.com, Apr 15 2018

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:59.0) Gecko/20100101 Firefox/59.0

Steps to reproduce the problem:
1. Go to: https://jsfiddle.net/tszynalski/kc2272ny/8/
2. Click the "Fade In" button

What is the expected behavior?
The cyan box should start fading in immediately.

What went wrong?
The cyan box does not start fading in until you move the mouse pointer away from the "Fade In" button.

Did this work before? Yes 65, maybe later

Chrome version: 68.0.3397.0 (Official Build) canary (64-bit)  Channel: canary
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: Shockwave Flash 29.0 r0

The problem goes away if the target opacity is changed from 0.99 to 1.

On my site, http://www.szynalski.com/tone-generator/ , there is a significant delay (several seconds) even if you move the mouse away from the button. To reproduce, try loading the page and clicking the "GET LINK" button.

Here's a screencast I just made that reproduces the issue. I tried it with --disable-extensions and --disable-plugins – doesn't help.

However, I can't reproduce the issue on http://www.szynalski.com/tone-generator/ anymore.

Rechecked the issue on latest canary 68.0.3397.0 using Win 7 and Win 10 on both corp and non-corp networks and unable to reproduce this issue. Hence removing Needs-Bisect label.

Could someone from Blink team please have a look at this issue.

Thanks!

Applying the style on the CSS before hand seems to work..

So far I've been unable to reproduce. Assigning to myself to check on our Windows lab when I'm back in the office next week.

dtapuska - does your note in comment #6 mean you were able to reproduce the bug?
My mac updated to chrome 66 now and I can't repro it but I did on 65 earlier today.

ngyikp@ - ah, excellent spot, thanks! Yes, this should be the same bug. I confirmed that if I force that feature on for my build, I can reproduce the problem. xidachen@ has turned down the experiment that was causing it, so it should be 'fixed' currently. (There is still an underlying problem that we'll need to actually fix.)
