Remote Debugging not working for inspecting mobile styles

I've noticed many times when using Chrome Inspect for web development that I can't get the right side (where the styles are displayed) to change when I click on different elements on the left side (the html). I usually refresh or close and reopen the browser to get it 'un-stuck' from the current element.

Now, I'm seeing this when using mobile inspect (via the Android SDK). It doesn't matter what element is highlighted... I can't change it! Even if I don't select anything, the <body> element is selected by default and I can't change it to another element. What can I do here? Is it a bug? I have to get back to working on mobile sites. I can use a 3rd party plugin for replacing Chrome inspect for regular web pages, but for mobile, I have no choice.. it just doesn't work.

I'm having this exact bug after upgrading to Chrome 40.0.2214.93 (64-bit) on Linux Mint Debian Edition. This previously worked fine, but now I can't select any elements in the Dev Tools on a Remote Debugging session to my Cordova app running on my device.

Note that debugging a mobile Chrome tab on the device, and debugging a regular web page, do not show this issue. It seems to only happen when debugging a WebView. It's as if the click event on the element in the Dev Tools isn't being registered.

Hmm... upon inspecting the inspector (Inception!), I get the following upon clicking an element in the original inspector:

Uncaught TypeError: undefined is not a function (inspector.js:696)

Appears to be within TreeElement.prototype.isEventWithinDisclosureTriangle. If I alter this function to return false; before anything else, on-click functionality to the original inspector is restored for that window (though the "disclosure triangles" don't work).

This appears to be a bug. I will file.

When you file a bug please provide a stack trace as well and copy the particular line where this happens (isEventWithinDisclosureTriangle method is quite long)

Glad I'm not the only one.... misery loves company haha. Your situation matches mine to a T. The only thing I can add is that It's also a problem with Canary (which I believe is also 64 bit).
