Headers are losing its format when containing numbers

[sojusnik]

Write "1. Header" in a note, press Strg+3 and then Strg+R. You'll see, that the header is not rendered properly - "1. ==== Header ====" is written there.

I suggest not to simply fix this particular issue, but implement full-featured numbered headers instead. I've been already thinking on that in relation with issue #1185182.

To be precise, this bug occurs when you format a list item as a heading.

When you first make the heading and then add the number, it does work as expected.

--> cause is that the list formatting is not properly cleared when formatting as a heading
