Edit View & Preview size start too small

When I open a file or make a new file and then open a new tab, the edit view font size is usually 8 now, which is the smallest. Also the Preview area can be the smallest or very big. I don’t think this was the case before.

It also happens to me in some situations or randomly.

Same here, tough I am currently not updating out of 1199 until next week. In 1199 it seems to be almost always like described.
