Uncaught ReferenceError: spyder_terminal is not defined

Description

What steps will reproduce the problem?

Output from bootstrap --debug (or internal console if not debug) shows a long string of Uncaught ReferenceError: spyder_terminal is not defined.

This occurs independent of whether the Terminal external plugin is enabled or disabled in Preferences. Perhaps unrelated: disabling Terminal plugin in Preferences does not seem to have any effect; it is still loaded.

All the above manifested with clean config files.

Ok, this looks annoying but not so serious to me. They are probably warnings emitted while the spyder-terminal server has not started yet and some JS library is looking for it.

I agree that this is annoying but may not be serious.

Checking this as @mrclary says even with the plugin disabled in the preferences it is getting loaded

This is kind of serious and we should try to address it before 5.3.0. Everyone else agree with that?

I agree. I’ll open a separate issue for it.
