Bug 1992365 [wpt PR 55196] - [SVG] Avoid throwing exception if UA can compute length via computed styles for `SVGGeometryElement`, a=testonly
Automatic update from web-platform-tests
[SVG] Avoid throwing exception if UA can compute length via computed
styles for `SVGGeometryElement`
According to the specification[1]:
If current element is a non-rendered element, and the user agent(UA)
is not able to compute the total length of the path, then throw an
InvalidStateError.
However, this also implies that if the UA is able to compute the
total length for a non-rendered element, such as by using computed
styles then an error should not be thrown in this case.
This CL addresses this scenario and ensures that no exception is
thrown when the UA can successfully determine the total length.
