 Issue 742633  has been merged into this issue.

Something still seems off in 61.0.3156.4. It seems a little better, but I'm having the following issues on badssl.com:
(1) In normal Clank, I can tap anywhere within one of the rows to navigate to a link. In VR mode, it seems like tapping inside the box (but not on the text) gets the link stuck in a hover state, and doesn't navigate.
(2) It's still sometimes hard to click on links. It doesn't happen always, but sometimes I try to click on a link (on the text itself) and have to click several times to get it to navigate. (I have similar problems on www.google.com so I don't the website is doing anything funny.)

I saw this as well on the same revision. It looks like it's at commit position 486205, which should include tiborg@'s change at 485956.

[vr] Apply content move suppression in UiInputManager

The change in https://chromium-review.googlesource.com/567384 did not
have exactly the same behaviour as the change in
https://codereview.chromium.org/2944453002. This CL moves the content
move suppression as per the previous CL and introduces a testing
framework for the UiInputManager.
