Searched My Bookshelf for some recipes. Switched to View As ≣ style, selected some lines then copied and pasted them into new topic I was writing. The pasted version of the lines were added as a bulleted list. Unfortunately the Preview option produces a blank space where that list should appear.
Steps to replicate the problem
Search for the terms "paul hollywood bake off" (without the quotes)
Switch to the ≣ mode of View As
Select then copy several of the results
Create a new topic in one of the forums
Type some text then paste the copied text in
Click the Preview button
The pasted text does not appear.
Switching to View As ≣ mode is not necessarry as the same non-appearance happens if the same lines are copied in the default format. (I was trying to report any issue entirely when I discovered this issue with ≣ displays.)
