markdown partly rendered even though disabled, wrong link warning

[r10s]

we do not want to render markdown at the moment -- it is still too experimental, it is not our current focus, and it is not supported on all platforms. having that partly supported weakens overall UX.

therefore, text should be rendered as entered.

however, for this is not aways true.

if one enters this is **bold**, *italic*, [link](https://delta.chat) one gets the following:

the link is rendered as mark down, but should not.

this is not a new issue, i just came over that when noticing another issue (as said, it is experimental or reasons, similar to location streaming :) - the other issue is that the upcoming dialog shows weird punycode, though the link does not require punycode:

at some point, we may focus on markdown, but that day is not today :)

tested on mac 1.50.1

hm, that seemed to be introduced unconditionally of the markdown switch at #1771. i find that a little bit questionable, these kind of things affecting the whole ecosystems should be regarded platform comprehensive. otoh, the expectation that time was also to go for message-parser rendering on all platforms soon, so a that time reasonable change.

but anyways, as it is now in since years, and getting rid of that may again introduce bugs, i am fine to leave link rendering as is, and only fix the punycode issue

you might mean this: deltachat/message-parser#88
does also affect normal links, not only labeled links.

Also adding labeled links was an intentional decision, there is explicitly a "desktop set" in the message parser (https://github.com/deltachat/message-parser/blob/master/spec.md#modes-of-the-parser) but the bug is not in labeled links only, it is more low-level as it seems to affects all links as stated above..
