Able to repro in Chrome 60 but not 59 or 61.

Can we get a per revision bisect?

Weird, I can repro in 61 (61.0.3159.0 (Official Build) canary (64-bit) (cohort: 64-Bit)).

Yes I can reproduce it in 59 and 61 as well. It is something to do with high dpi devices I believe. Are you using a hdpi device?

It is actually broken in Edge for me as well so I believe this is a site issue.

I'm not using high DPI; just 100%.

it works perfect fine in edge for me though? http://i.imgur.com/1MJpnYx.gif

But I indeed can reproduce it on 59 now too. 

Dunno why I can't before, maybe I was on a different computer at the time. 

Ok, I just find that I can NOT reproduce it on either of 59, 60, 61 in my another Win 7 computer.


About the high-DPI: the laptop with Win 10 that I CAN reproduce this bug, is indeed hdpi. HOWEVER, I use an external display exclusively (the screen of laptop is totally not used, the project setting is "second screen only") with normal DPI (and 100% zoom in Windows setting). I don't know if this is related to the problem.

Does it reproduce as well in Edge with the hdpi display ?

Tested the issue using #60.0.3112.66 on Win 10, Mac 10.12.5, Linux Ubuntu 14.04 as well. Able to zoom in and out on clicking on the thumbnail.

Note:
1. Issue is not seen using #59.0.3071.115 , #61.0.3161.0 on Windows 10 dual Monitor.
2. Issue is seen using #59.0.3071.115 , #61.0.3161.0 on Windows 10 DELL M3800 laptop (HiDPI). Observed on clicking on Thumbnail nothing is happening.
3. Issue is seen in FireFox browser as well on Windows 10 DELL M3800 laptop (HiDPI). Observed on clicking on Thumbnail nothing is happening.
4. Removing Bisect label for now. Please add it back if required.

Please confirm the behavior.

Thanks!!

Did one more testing, found something new.

First, please clarify what do you mean by "HiDPI" in Windows: if my default scaling option is 125%, is it considered as HiDPI? My laptop is not nearly as high DPI as your Dell one, it's just a 1080p on 15" display. But the default setting is 125% scaling, so I don't know if this is enough to show different result from yours.

But for now, my testing result shows:

1. This is irelavant to my "scale and layout" setting. Can reproduce on both 100% and 125% (I restarted computer after each change) on my built-in screen, or 100% with an external monitor.
2. I can only reproduce it on my Win 10 laptop, not on my Win 7 desktop.
3. About Firefox: I found that if Electrolysis is enabled, yes you can reproduce it as well. Mine was disabled so I didn't found it before. Haven't test on Win 7, though.

kraush@ This appears to be a site issue that occurs across browsers. I'm not sure how to long an issue against the amazon property are you able to help with that?

HiDPI is the scaling of the display you have. Some laptops have hdpi whereas a desktop typically won't. The display is denser in terms of the number of pixels per inch.

This clearly is an amazon issue at hdpi in all browsers it seems.

Thanks, but does Windows' "scale and layout" option (when it's beyond 100%) count as hi DPI? Or it's a inherent "property" of hardware only (well, 1080p 15" screen obviously has much higher DPI than a 1080p 24" desktop monitor)?

Anyway, just to make it clear (as I mentioned before): I do agree with you it has something to do with hiDPI, but it doesn't only happen when using hiDPI, as I can reproduce the problem using a 100% scale, external normal DPI monitor (albeit connecting to a supposed hiDPI laptop).

Thanks for the help!
