2. Have a target (e.g. <a name="link"></a>) further down a page.
3. Click the link.

The browser window scrolls to the named anchor.

What went wrong?
The browser will not scroll to the target location.

Does it occur on multiple sites: Yes

Chrome version: 55.0.2859.0  Channel: dev
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: Shockwave Flash 23.0 r0

The problem is not present in any other browsers, but I wanted to post this as a new bug because it works fine in stable (53.0.2785.113). It looks like a regression.

Defining a CSS rule later that sets the overflow to something other than hidden does not fix this behaviour.

Found in a WordPress theme with 54k sales. I have no idea how prevalent this usage is elsewhere.
