Adding Text Color to AlloyEditor and using it will cause a scrollbar to be removed.
Steps to reproduce:
1. Deploy plugin found in LPP-38914
2. Go to Web Content and add a new web content with a lot of text or enough lines to make a second scroll bar appear on the right side of the page (see screenshots).
3. Highlight text and apply a text color
One of the scrollbars is removed.
No scrollbar gets removed.
