The test suite should not make assumptions that don't hold true
if the user has adjusted commonly-available preferences.

Therefore I disagree with changing the policy and the number of
tests that rely on this assumption should be kept to a minimum.

Furthermore, there is no benefit to making this assumption.
Tests are equally, if not more, readable and reliable by using
units that do not rely on the font size.

Please be clear that we are not authoring web pages here.
We are authoring tests. Good practices for tests are not always
good practices for web pages, and vice versa.
