Bug 234139 – [WPT] test_driver.Actions() not working properly

• Status: NEW
• Component: Tools / Tests

[Manuel Rego Casasnovas]

In several WPT tests that are using test_driver.Actions() we get the following error:
	ReferenceError: Can't find variable: action

This is a list of tests with such error:

It's worth noting that these tests run fine in wpt.fyi:

So it's the reference to action at https://github.com/WebKit/WebKit/blob/eb14e0ccb41166c7509ce8b445d4e663a1dfd31a/LayoutTests/imported/w3c/web-platform-tests/resources/testdriver-vendor.js#L264

Blame claims it's a regression from https://github.com/WebKit/WebKit/commit/95ae6591e8f12d43817a52ad728e9c438bf9a0cc, bug 197101.
