Spoiler quotes might be messed up. They break when multiple lines of spoiler are involved. This is inconvenient on sites like Scifi, where spoilery plot details might be discussed, or Puzzling, where some members are picking up a convention of spoilering their answers.
I'm assuming they're intended to work with multiple lines, since regular quotes do and the editing help says nothing either way.
This is what spoiler syntax looks like when it's working just fine:
>! See here
It shows up as:
Now to the bugs.
Multiple lines, blank line in between
>! This line is visible, it's just a quote
>! So is the exclamation mark
! This line is visible, it's just a quote
! So is the exclamation mark
Multiple lines, no blank line
>! In quote markup, you can put >'s in the blank lines.
>! When you do that in spoiler quotes, the entire thing becomes one line.
In quote markup, you can put >'s in the blank lines. When you do that in spoiler quotes, the entire thing becomes one line.
