Breakout from http://crbug.com/590856 -- unsure whether related, but potentially plugin resize lifecycle issue, and so filing for subsequent investigation.

Repro steps:
- desktop debug build, config'd to handle plugins like android (see patch below, which may or may not actually be required)
- open deepika.com, scroll around, open dev tools, size to Nexus 5X with the device simulator button in the dev tools top button bar, scroll around, close dev tools which will cause page to resize to normal desktop size

[1:1:0304/163213:FATAL:render_widget.cc(1090)] Check failed: !params.needs_resize_ack || !next_paint_is_resize_ack().
