Twenty Nineteen: Text Color issue in Pullquote Block

[kajalgohel]

In Twenty Nineteen Theme, when we add Pullquote block in editor side, and choose text color, We can see that the text color is not reflected for "Add citation" text.But when we see the same Pullquote block at front side, text color for "Add quote" and "Add citation" is not reflected.

Steps to replicate:
1: Activate the Twenty Nineteen Theme
2: Add Pullquote block
3: Enter some Text for "Add quote"
4: Enter some Text for "Add citation"
3: Choose Text color
4: Save Page/Post
5: View the page/post at front side

For better understanding I provide video attachment link.
