David Grogan f678a6a648 Bug 1616730 [wpt PR 21893] - [FlexNG] Don't let min size go negative, a=testonly
Automatic update from web-platform-tests
[FlexNG] Don't let min size go negative

We were subtracting border_padding when it wasn't present if the item
had min-size:auto but didn't qualify for the special flex min-size:auto
behavior because, for instance, it has overflow: hidden.

This fixes the telemetry_perf_unittests failure FlexNG was hitting on
the bots, which was caused by a recorded google docs page.
