The markdown filter does not handle html tags properly.

Created by: nmihai_2000

One would expect that markdown and the equivalent html constructs would result in the same extracted events (including codes in TextUnits), but it does not.

For example these two lines should produce the same events:

This is a [link](foo.html).

This is a <a href="foo.html">link</a>.

and same for these two lines:

This is a **bold**.

This is a <b>bold</b>.

The open-close html tags produce 2 standalone codes, instead of open-close.
And the link is even worse, it produces 2 TextUnits, one with This is a and the second one with <x/>link<x/>.
