Currently we do 2 pass updation. first we scan through all the styles
and check if they have text_style which matches the test_style we need to update
then we mark them dirty. then we call style_all_update() to go through the list
again and update those styles.
By combining them both in a single function we avoid scanning through the whole
list again.
