When a page has a larger content, if the user tries to copy and paste it, it will not paste any data, as if no content has been copied.

Steps to Reproduce

1. Create a very large page in Confluence.
2. After having all the content added, try copying all or a good part of it.
3. Paste it on the same or a different/new page.

The content should be pasted.

Actual Results

Nothing happens. The following error is displayed at the network console:

[Violation] ‘paste’ handler took XXXXms 

Workaround

Reduce the number of content being copied and pasted.
