Unexpected behavior of context selector when copy and pasting prompts

Problem

Unexpected behavior of context selector when copy and pasting prompts from one tab to another, which causes either the context file to not be picked up (first try) or actually deletes some parts of the prompts (second try).

Steps to reproduce the issue (see VIDEO)

1. Open a tab (in my case using /dev agent), write a prompt which uses at least once the context selector (for a file in my case)
2. Copy the sent prompt
3. Open a new tab (normal tab)
4. Paste the prompt (the context selectors won't pick up the context files from a copy-paste)
5. Select the non-rendered non-identified context from the @ symbol to the end of the file name
6. While keeping the selection type a @ which will delete the current selection and add a @ to the prompt
7. after the @ write the name of the file (pick up from shown context selector list of files)
8. PROBLEM 1: The file wont be identified as context (at least ui-wise)
9. Repeat from step 5 to step 7 on the newly written @ and filename
10. PROBLEM 2: The file will be identified as context but will delete part of the input prompt preceding the context file

Expected behavior

Context file is picked up immediately without deleting any part of the prompt
