Minor UI bugs (posts content)

1) wrap in box doesnt display properly on smaller screens after setting medium or small size (it should resize back to big after some viewport breakpoint so the content can fit better) 🤔

2) if you change the wrap in box size, it always shows big as selected option in the settings menu 🤔

3) i dont understand why is it called Big big, Medium medium and Small small 🤔 And same goes for Inline regular, Left Wrap left and Right Wrap right in box wrap settings 🤔

4) close button clickable area in image lightbox overlay doesnt match its content (x) and its not properly positioned in the top right corner

5) incorrect border bottom radius in post edit reason

6) when i edit a post (this) with some video, it adds extra <p> before each video 🤔 but i was just adding 5) and 6), nothing related to the area with videos 🤔
