Font colour is overwritten when used with Bold on Paragraphs

## Issue Description
I created a column block with a Paragraph inside. The background is red and the font colour is white and bold.
This displays correctly in the editor but on preview ( I haven't published the page yet) the text colour displays in grey.

When I remove the bold (or strong tags) the text displays with the correct colour.
I guess the bold styling is overwriting the colour perhaps 🤷‍♀️

## Steps to reproduce:
Create a paragraph, with a BG colour and a colour (not grey) make the text bold. See on the preview that your font colour is not the one you selected on the editor.

## Expected Result:
The colour should be the one I selected, not grey.
