We don't want to move to this yet, as the SDKs aren't even updated to
use them, so it can be confusing when you see the failures.

Before this commit, text sections of parsed markdown were not properly
escaped, e.g. an ampersand (&) in a text would end up in the final pango markup
unescaped, causing pango to fail parsing the markup.

With this commit, all leaf parts of the markdown (those that end up in the pango markup)
are now escaped.

We need to rely on transient settings to remove this.
