JS tests random failure with "test caused a page reload" error

[Alberto Donato]

Javascript tests sometimes fail with the following error:

Chromium 65.0.3325 (Ubuntu 0.0.0) ERROR
  {
    "message": "Some of your tests did a full page reload!",
    "str": "Some of your tests did a full page reload!"
  }

This seems to only happen when multiple browsers are used together (even if concurrency is set to 1 and they're run sequentially).

Is this still an issue?

[Alberto Donato (ack)]

Since we switched to running tests sequentially with different browsers (instead of running them in paralel) I haven't seen the issue anymore.
