imported/w3c/web-platform-tests/svg/linking/reftests/url-reference-local-textpath.svg

Rarely flaky since added. Became much more frequent since first failure in r269568. GTK also with the rare flakiness with a similar diff.

Could not reproduce it locally.

Checking with the browser, the reference 100x100 green square is correctly shown, both GTK and WPE. The mac expectation also has RenderSVGRoot dump as 100x100.

Shouldn't WTR show the RenderSVGRoot with 100x100 instead of 72x102? This looks like some discrepancy between GTK/WPE WTR and the actual browsers (including MiniBrowser).
