Subject: [PATCH] Remove line breaks when displaying file names in the project
 panel (#10231)

- Fixed #8603

For the label title of the project panel, I find that there is no place
to use to get the title of the label to do some operations, it should be
safe to modify it, but I'm not sure how we need to modify the problem, I
can think of two scenarios:
1. Modify every place where you don't want multiple lines to appear
2. Make the label only display a single line (e.g. provide a new
parameter, or a new label type?)
