Thanks for the report. 

The above issue is reproducible on All-OS (Windows (10 & 7), Mac 10.11.4 & Ubuntu 14.04) with chrome versions : 50.0.2661.102(Stable), 51.0.2704.36(Beta), 52.0.2716.0(Dev) & 52.0.2729.3(Canary).

It is very hard to reproduce on Mac & Linux but the memory increase when steps one is performed.

This is a non regression issue as can be seen from M30 build - 30.0.1549.0. Hence marking the same as Untriaged.

This isn't inherently a performance issue. The issue is that the logic to hide/show the tooltip is running repeatedly, possibly because of the logic on the website itself.

Adding input folks to see if there's a Chrome bug here.

Is this occurring with a completely stationary cursor?

The page is doing something like https://output.jsbin.com/yufoqi/quiet, which flashes when you move your cursor along the bottom of the red box.

We have raf aligned the input since then which causes the CPU usage to go down. But at the end that is the web site logic to do an action again and again and there isn't much we can do about it.
