The problem:
There are two issues with copy/paste text with tags:
#1

• open segment target for editing
• copy part of text containing tag(s) from segment source by selecting it and pressing ctrl+c
• without clicking into editor press ctrl+v
• as a result we will have the div/span markup in the editor instead of proper tag

#2

• open segment target containing whitespace tag for editing
• select part of the text with the whitespace tag with ctrl+c
• open another segment that doesn't have any tags in it
• paste content with ctrl+v
• save segment
• as a result we will have the tag sent to the server as img markup instead of our div/span#

#3

• Open segment A, copy the segment content from editor
• Close and open segment B, select all, insert the previously copied content
• Save segment → the inserted imgs tags are saved to the backend producing an error there
• Solution: remove inserted img tags which are not present in the tagmap
