Prevent send message icon from breaking on sending a message

[cpba]

After 4dda195 the icon would no longer match the one defined in the glade files.

This doesn't appear to completely fix the issue, the icon still breaks for a short instant while the message is sending, then recovers afterwards.

Is there supposed to be a different icon while the message is being sent?

he icon still breaks for a short instant while the message is sending, then recovers afterwards.

Yes, because the neither "dialog-cancel" nor "dialog-ok" is not freedesktop standard icon so that are not include in adwaita icon theme.

I think the standard theme has too few icons so that nothing can be expressed.

Yes, the freedesktop standards really don't cover much, it's just meant to be a base for interoperability.

If it's only a temporal fix until srain gets its own icon, would you consider using something like mail-send-receive? mail-forward or perhaps mail-replied could also work.
