Tag Wiki Excerpts support ~ 450 characters, but Tag Wiki dropdowns only display ~ 300 characters. The remaining characters are truncated.
This would not be a problem if the tag excerpt was used merely to describe a tag. But the tag wiki excerpt is also used to describe proper use of the tag as well, because it puts this information front-and-center when the tag is hovered.
It sometimes takes some pretty creative writing to get that information to fit into 450 characters, only to find out that the last 150 or so characters are being cut off in the hover dropdown.
This effectively limits the useful size of a Tag Wiki to 300 characters, and complicates the editing process, because you have to experiment with repeated edits to get it to fit onto the dropdown.
I suggest that we either increase the size of the Tag Wiki dropdown to accomodate all 450 characters of the Tag Wiki Excerpt, or limit the tag wiki excerpt to 300 characters.
I also suggest that we preserve line breaks in the Tag Wiki Excerpt, so that we can separate the paragraph that describes the tag from the paragraph that describes its proper use.
