Then the older bug may be cancelled as a duplicate.

I meant a custom user filter. I consider zero width spaces as the last 
resort. Nicolas considered making zero width spaces an official part of 
syntax stripped during export and a way to preserve some of them. In the 
case of links I still prefer breaking emphasis at the link borders. 
`org-insert-link' may check after inserting the markup if it is parsed 
as a link and add more markers if necessary. Unfortunately it is not 
always possible. In the following case

    /inter[[https://orgmode.org/?oops=1][word]]link/

additional markers would not work (unless augmented by zero width 
spaces, but at least they will be outside of link target)

    /inter/[[https://orgmode.org/?oops=1][/word/]]/link/

However mostly it is a decent workaround since links are usually 
surrounded by spaces. At certain moment I was surprised that emphasis 
markers are not recognized at the borders of export snippets and they 
are active one at one side of links.

I am afraid that zero width spaces in link targets may lead to confusion 
of users since in the most cases e.g. http: URLs may be pasted to 
external application as is.
