Non-helpful flash message when attaching file fails
When attaching a file to a comment fails, a flash message is shown which doesn't help the user but looks only cryptic. Also the style of the flash message doesn't match other flash messages (see also #19160 (closed)).
Steps to reproduce
- navigate to page with comment form, e.g. any Issue
- turn off network connection
Attach a filelink and select any file
- receive bacon
Use something like
Attaching the file failed. Server responded with error code 0.
Actually, even that is not ideal because in case of missing network connection, the server doesn't respond at all (hence the error code 0).
Additionally, this flash message could be moved above the text area as in !4854 (merged).
