Skip if this text has no shadow.
Test passes if there are no pink lines between joined characters.

Assertion: [exploratory] text-shadow on cursive Arabic text doesn't break the joins

• text-shadow is set to -6px 4px 2px pink.
• The 'skip' directive checks that text-shadow is supported. If not, the test is invalid.
• The default test uses the Noto Naskh Arabic webfont, but the font change control allows you to test whether particular fonts make a difference to the outcome.
