* web-platform-tests/html/semantics/embedded-content/the-img-element/sizes/parse-a-sizes-attribute-expected.txt:

Source/WebCore:

It shows all subtests passing but that is a bug. We don't even support all the unit types.
The test occasionally fails when reloading, that failing results are actually the correct ones.

* css/parser/SizesAttributeParser.cpp:
(WebCore::SizesAttributeParser::SizesAttributeParser):

    Ensure we have correct size for the iframe before parsing 'sizes' attribute values. The interpretation of
    these may depend on the iframe dimensions.

+        It shows all subtests passing but that is a bug. We don't even support all the unit types.
+        The test occasionally fails when reloading, that failing results are actually the correct ones.

+        * css/parser/SizesAttributeParser.cpp:
+        (WebCore::SizesAttributeParser::SizesAttributeParser):
+
+            Ensure we have correct size for the iframe before parsing 'sizes' attribute values. The interpretation of
+            these may depend on the iframe dimensions.
