When copying a table from one page to another on our wiki (https://se.wikimedia.org/) using VE a few lines of codes are added into the wikitext of the table. The links added in the wikitext occur later on the target page.

To summarize the video, you copy-paste some rows of the table here: https://se.wikimedia.org/wiki/Projekt:Wiki_Loves_2018#Tidplan, then delete some cell contents, switch to wikitext, and get a table with href attributes on some cells and rows. I couldn't reproduce this, so it might be already fixed (we fixed some copypaste bugs recently), or it might depend on the browser or something.
