CanvasResource_GpuMemoryBuffer was not refreshing its
sync token when new content was added, resulting in recycled
buffers never getting their contents flushed.

I hastily landed and merged a quick fix in order to unblock the dev channel release. A proper CL (duly reviewed, with tests) will go into trunk in coming days.  

I am going to keep this bug open until the work is complete, but we can consider Dev release unblocked at this point.

Verified the fix on Mac 10.13.1 using Chrome dev version #65.0.3299.0 with steps mentioned in comment #0. Attaching screen cast for reference.

No Flickering of contents is seen on scrolling and able to select particular cell successfully. Hence, the fix is working as expected.

Adding the verified labels.

Issue is no longer reproducible on 65.0.3298.3 dev as well. Hence adding TE-Verified-65.0.3298.3
