The weird quirks when trying to make a title a slightly larger font size than the text in the body of a post. Like you quote part of an article in a thread and have the title slightly larger. Sometimes it works, sometimes it does not. Sometimes it works, then you try to edit the post, and not even the part where it has the title set to 15 or something, like when correcting spelling on a non related word in the post you are editing then it suddenly refuses to let you save until you make the title font the same size as the rest of the post even though you didn't touch that in your editing. It is whack.
For example:
The Smurfs
The Smurfs (French: Les Schtroumpfs; Dutch: De Smurfen) is a Belgian comic franchise centered on a fictional colony of small, blue, human-like creatures who live in mushroom-shaped houses in the forest. The Smurfs was first created and introduced as a series of comic characters by the Belgian comics artist Peyo (the pen name of Pierre Culliford) in 1958, wherein they were known as Les Schtroumpfs. There are more than 100 Smurf characters, and their names are based on adjectives that emphasise their characteristics, such as "Jokey Smurf", who likes to play practical jokes on his fellow smurfs. "Smurfette" was the first female Smurf to be introduced in the series. The Smurfs wear Phrygian caps, which came to represent freedom during the modern era.
It allowed me to post this THIS time. But when editing it may not allow me to save it sometimes when changing something else entirely if I do not change the larger font size in the title. You never know when it will do this either as it seem to be random..
