Do the spoiler insertion symbols work correctly?
When I click the insert spoiler button, the characters are displayed >!!< , but the content is not hiding under the spoiler.

However, if you write >!! then a spoiler button appears, but after opening, there will be a "!" first, and then hidden content.

>! displays nothing
P.S Also, no matter how many line breaks you do with the ENTER key after >!! there will be no gap
