1585226 - Chromium gamepad API tests assert when ran locally.

Status: RESOLVED DUPLICATE of bug 1585068

(Core :: DOM: Device Interfaces, defect)

Description

[Emilio Cobos Álvarez (:emilio)]

A test like https://cs.chromium.org/chromium/src/third_party/blink/web_tests/gamepad/gamepad-works-after-open.html?l=1&rcl=acc5363da5b3731b82eed0938a92314c2c8db54c, when ran locally (needs a couple referenced files but it should be easy to reconstruct it locally) like:

./mach run file:///home/emilio/src/chromium/src/third_party/blink/web_tests/gamepad/gamepad-polling-access.html

(use the relevant path)

Crashes locally with:
