Bro, you should not merge the master into your branch, you need to rebase your branch. (read more about it here).

I think you need to recreate your branch.
Everything looks green, but merge button is disabled.

[k0psutin]

Ah sorry about that. I reverted the merge and rebased. Hopefully it works now.

[k0psutin]

The tests should be okay - I couldn't run the golden tests because of the pixel test failed. I mentioned about this at #1468. I ran the other tests separate from the golden files and they were ok.

[imaNNeo]

You're right, I just removed the golden tests for now 0ae88cf. I need to learn more about them in the future.
Please rebase one more time

[k0psutin]

Now it is rebased again and fixed the test to use TextScaler
