Want to point out this bug again since it has been about 4 years:
Copying and pasting it exactly as it is since the bug is still the same with same way to reproduce:
Steps to reproduce
If you want to signal that hyperlink mentioned is not in force anymore, it is good to cross out the text.
~~ https://www.zakonyprolidi.cz/cs/2006-137~~ — this law is not in force anymore
Expected result
In preview mode, it works correctly.
In edit mode, I expect that the hyperlink is crossed out, but it is not.
Actual result
The first tilde symbols are crossed out, the hyperlink is “untouched” and a subsequent text “this law…” (in my example) is crossed out even it should not.
Crossing out text that is not a hyperlink works properly.
