Flash player downloaded when Flash content disabled

Issue description
UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36
Steps to reproduce the problem:
1. Have a profile without Flash ("internal-not-yet-present")
2. Disable Flash in Content settings
3. Visit a page with a Flash object
What is the expected behavior?
The Flash content appears as the click-to-play prompt.
What went wrong?
Chrome downloads and installs Flash.
Did this work before? Yes 55, when Flash could still be reliably disabled globally.
Chrome version: 56.0.2924.87 Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 24.0 r0
I'm not exactly sure what happens after the download, because I have taken steps (replaced the User Data/Pepper Flash directory with a regular file) to prevent Chrome from successfully installing Flash, but it appears likely that the click-to-play prompt would appear once it has installed the plugin.
There is no reason to even attempt the download with the content setting set to block until the user indicates that the content should be displayed.
As for the "expected behavior" above, that is not what I would like to see, but what I expect to happen in 56. My preferred behavior is to have the jigsaw thing say "Flash is disabled" and leave it at that.

Unable to reproduce this issue on Windows-10 using chrome latest stable M56-56.0.2924.87 by following steps mentioned below. 1. Navigated to chrome://settings/content 2. Blocked sites from running flash 3. Navigated to sample webpage http://www.adobe.com/devnet/actionscript/samples/drawing_6.html 4. A yellow pop-up displays on top saying to 'Update plugin' and 'Run this time' 5. Clicked on 'Run this time' and observed the flash content plays as expected without downloading flash. chris@ Could you please let us know the above steps is the right way to reproduce this issue? Are you able to play the provided flash content in your machine? If yes, could you please let us know on which site are you facing this issue? Thanks!

If yes, could you please let us know on which site are you > facing this issue? My reproduction steps are in my original report. No, I'm not "able to play the provided Flash content", nor do I want to be. My point is that Chrome starts downloading the Flash plugin as soon as it encounters the Flash object on the page. At this point, it knows that it is not supposed to run it (because the content setting is set to "block all"), so it should not attempt to install it. I do not get any yellow pop-ups, either. Are you sure that the Flash plugin was not already present in your profile, in an outdated version?
