Thanks for filling the issue...

Unable to reproduce the issue on reported chromium version 68.0.3440.106 using Ubuntu 14.04(Wayland).
Steps: 
---------
1. Launched reported chrome 
2. Resized the browser window and moved cursor inside to outside and out side to inside of the browser as per comment #0  
As we are observed that mouse cursor updated to resize type at the window border
@Reporter: Can you verify this issue with fresh profile that is not having any extensions and apps or reset all the flags. Let us know whether issue still persists.

Thanks.!

Emm, I'm removing the triage labels from this bug as long as it's only related to Ozone/Wayland project. Me and jkim are working on it.

The bugs created here and only for easier management of the tasks we have.

And jkim is actually taking care of it.

Reset the cursor from WindowTreeHostPlatform on ET_MOUSE_EXITED

When the mouse cursor exits from the browser window,
'CompoundEventFilter' doesn't update the cursor and it doesn't
know whether ET_MOUSE_EXITED happens when the window is destroying
or the mouse exits from the window. WindowTreeHostPlatform keeps
the previous cursor and WaylandWindow, one of PlatformWindows,
also keeps it.

This patch resets the cursor from WindowTreeHostPlatform on
ET_MOUSE_EXITED to update it when it reenters the window.

jkim, I guess it is fixed now. Can we close it?
