What did you do?

We've a TTML caption formatted as:

<div>
    <p begin="00:00:01.800" end="696:15:11.521" xml:id="s0" region="r" style="p">
        <span style="style1">Hej, lilla gumman.</span>
        <br/>
        <span style="style2">– Vilket fint italienskt hus ni har!</span>
    </p>
</div>

What did you expect to happen?
That it should render two caption lines, with no empty line in between.

What actually happened?
See attached image., it renders three lines, with an empty line in between from the <br/> tag.

I haven't been able to understand from the spec what should happen in this scenario and if the formatting is wrong, but I can see that dash.js, rx-player and the IMSC1 Renderer (which I'm not familiar with but saw it linked in another issue) renders the captions without the line in between.

What do you think?

You are correct. I'm working on other TTML parsing and rendering fixes, so I'll work on this, too. Thanks for filing!
