Bug 305501 – [WPE] Test platform/glib/non-compositing/simple-dom.html is a flaky failure

• Component: WPE WebKit
• Status: NEW

[Carlos Alberto Lopez Perez]

The test platform/glib/non-compositing/simple-dom.html is very flaky in WPE (fails 50% of the time), however in GTK passes almost all the time.

The issue is easy reproducible by running the test several times with WPE
