In this Hebrew Wikipedia edit a <nowiki/> tag was added without any apparent reason.

It appears after a link, and it's common to add nowiki if no space was typed between a link the text after it (see T141689), but in this case there is a space after a link.

It's imaginable that the user initially forgot to type a space, which got the <nowiki/> added, then the user add a space and the <nowiki/> tag was kept, but I couldn't reproduce it.

And here is another example from the same day, although unlike above, in this example the link itself was added in the same edit.
