[WF] Fix: Clear floating environment

[leboem]

Please, check if this fixes the moving images bug

It looks like the images now stay in place. But with multiple refreshes there is a huge white space between two sections (eg, in the DD post).

For example:

• Open the DD post
• Scroll down to the logic gates section
• Reload (possibly multiple times)
• A big blank should appear above
