REGRESSION(r222843): [HarfBuzz] Combining enclosed keycap not correctly handled

• Component: Platform
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

While working on bug #183155 I realized that the first emojis shown in http://www.fileformat.info/info/emoji/browsertest.htm were not working. This is because we are not correctly handling the combining enclosed keycap since we switched to use ComplexTextController.

This shouldn't be in the expected results. Why is this in the expected results? WTF?

Oh! This is because of resource load stats always enabled in tests. It queries the plugins data and stupid flash plugin spits that to stdout when loaded, making all my non-ref tests to fail, btw.
