Textblock: Fix padding with styles (part 2)

Summary:
If ONE single item in the whole textblock has a padding of k,
then ALL the lines of the textblock will be padded by k pixels.

Here's a solution to add the padding only to the first line.

Test Plan:
Write any multiline text, without styles, in an entry.
Add some glow to one element. All lines should be spaced by
an extra 2 pixels.
