calc - "To paste outside Nextcloud Office, please first click the 'download' button"

[gerbrent]

Describe the bug When copy-pasting from Nextcloud Office calc, I often get an error message when pasting the content elsewhere (i.e. local text file): To paste outside Nextcloud Office, please first click the 'download' button

1. the phrase please first click the 'download' button is very misleading in this context - there is no download button! What does this mean in this context? Confusing for the user.

2. This behaviour is... seems intermittent: on the same internet connection it occurs for some copy-paste tasks, but not all. Given I'm typically copy-pasting text from calc cells, this seems inconsistent and unnecessary?

issue has been persistent for 1 year+

To Reproduce Steps to reproduce the behavior:

1. open calc doc w lots of text in cells (i.e. social media-length text, ~280 characters or more)
2. double-click a cell into edit mode
3. select all text (ctrl-a)
4. copy (ctrl-c)
5. paste into text editor locally

Expected behavior Paste the text in clipboard (i.e. the text that was copied from the cell)

** Actual behaviour ** text pasted is: To paste outside Nextcloud Office, please first click the 'download' button
