-PASS Verify that writing to the width and height attributes of an OffscreenCanvas works when there is no context attached.
-PASS Verify that writing to the width and height attributes of an OffscreenCanvas works when there is a 2d context attached.
-PASS Verify that writing to the width and height attributes of an OffscreenCanvas works when there is a webgl context attached.
-PASS Verify that writing to the width or height attribute of a placeholder canvas throws an exception
-PASS Verify that writing to the width or height attribute of a placeholder canvas throws an exception even when not changing the value of the attribute.
-PASS Verify that resizing a 2d context resets its state.
-PASS Verify that setting the size of a 2d context to the same size it already had resets its state.
-PASS Verify that resizing an OffscreenCanvas with a 2d context propagates the new size to its placeholder canvas asynchronously.
-FAIL Verify that resizing an OffscreenCanvas with a webgl context propagates the new size to its placeholder canvas asynchronously. assert_equals: expected 30 but got 10
-FAIL Verify that drawImage uses the size of the frame as the intinsic size of a placeholder canvas. assert_equals: expected 10 but got 1
