Are constantly text failing in macOS Debug on Apple Silicon only. 

HISTORY URL:
https://results.webkit.org/?suite=layout-tests&suite=layout-tests&test=svg%2FW3C-SVG-1.1%2Fpaths-data-03-f.svg&test=imported%2Fw3c%2Fweb-platform-tests%2Fsvg%2Fimport%2Fpaths-data-03-f-manual.svg

While only one test notes that it is imported, both tests appear to be imported tests from MIT.

Here is the text diff for the first test. The diff for the second test is very very similar. I have also attached both diff files to the bug:

These tests only fail on Apple Silicon Macs, and as such I cannot reproduce the failures because I do not have access to an AS Mac.

Updated test expectations to [ Failure ] while test is being looked at.

Looks like a rounding issue, but a pretty large one: 457.102 vs. 457.101.

imported/w3c/web-platform-tests/svg/import/paths-data-03-f-manual.svg is no longer a failure, removed the expectation in 277362@main.
