The changes look good in but can you clarify the questions I left in the comments.

[SergioEstevao]

Can you explain why do we need this IF, in what scenarios the tailIdent can be positive or negative?

[azone]

Here is Discussion of tailIndent from apple:

If positive, this value is the distance from the leading margin (for example, the left margin in left-to-right text). If 0 or negative, it’s the distance from the trailing margin.

For example, a paragraph style designed to fit exactly in a 2-inch wide container has a head indent of 0.0 and a tail indent of 0.0. One designed to fit with a quarter-inch margin has a head indent of 0.25 and a tail indent of –0.25.

[SergioEstevao]

So could we rewrite like this:
padding += abs(paragraphStyle.tailIndent) + abs(headIndent)

Closing in favor of #828.

Thanks a lot sir!!

@jleandroperez - Just double checking... this is the issue and #828 is the PR for this report. Is that correct?

[jleandroperez]

@diegoreymendez Nope! #796 is the issue. #828 is Sergio’s fix Mark II, while this one is the original PR (AKA Fix Mark I).
