Issue Summary

When using the Legacy editor, if a heading row or column is using a custom background color and contains a paragraph, the text background will be grey and will not match the cell background color.

Steps to Reproduce

Steps:

1. Create a new page using the Legacy editor
2. Select one of the heading row cells and add some text
3. Use the 'Change cell color' icon and select a custom color
4. Use Enter or Return to add a paragraph to the colored cell

Expected Results

The heading cell will preserve the background color.

Actual Results

The text background color turns to grey regardless of the cell background color.

Workaround

The available options are:

1. Use a Line Break (Shift + Enter / Return) instead of a paragraph (Enter / Return) as it does not trigger this Bug
2. Remove the heading value using the 'Heading row' and 'Heading column' buttons as non-heading cells are not affected by the Bug
3. Convert the page to the new Cloud editor as it is not affected by this Bug
