Long code reviews don't render properly in Gerrit

Project Member Reported by kbr@chromium.org, Mar 7 2018

Issue description

Google Chrome	67.0.3362.0 (Official Build) canary (64-bit)
Revision	bc0fc7083e5466f5227bc868c2543957672def9a-refs/heads/master@{#540777}

On Canary on a Retina MacBook Pro, multiple long code reviews I've viewed today display large blocks of white where side-by-side code should be.

https://chromium-review.googlesource.com/902762 is one example. In Canary, expand all the diffs and look at the diffs for 
content/browser/renderer_host/input/render_widget_host_latency_tracker_unittest.cc . Part way through it's truncated. See attachment.

https://chrome-internal-review.googlesource.com/583823 (sorry, Google internal only) is another simpler example. It's a single modified file and it's truncated partway through.

It looks like this is just a bug in rendering; interaction with the white region appears to be correct.

This is a major regression. I'm not sure when it crept in. Hopefully this is a duplicate but if not it needs to be bisected and diagnosed.

I can't reproduce in 67.0.3364.0 on Mac Retina. We did have issues with missing content on scroll that were fixed yesterday, so maybe this is a duplicate.

kbr@, can you try again?

Yes, thanks, confirmed working again in:

Chrome	67.0.3364.0 (Official Build) canary (64-bit)
Revision	92107f0efb261174280c88aaac88e3cd64469793-refs/heads/master@{#541279}

Could you please duplicate this into the other bug? Thanks.
