Reproduce following steps below:
- Input some text into a cell of a table
- Copy some other text and try to paste them right after the text of step 1
Result: Can not paste the text into the same cell.
Note: If selecting whole cell then paste, it works by replacing the existing text by the copied text, however, I think it is inconvenient. Because, sometimes, I want to add more content with existing one, not replace.
The same issue with texts in the sticker or other objects.
