Allow to invoke inline completer anywhere (not only at the end of line)

[ajbozarth]

References

Fixes #16295

Code changes

The inline completer prevents automatic running of the completer when not at the end of a line of code, but it is also applying this when invoked manually, which was unintended. This addresses that bug.

User-facing changes

Allows a user to manually invoke the inline completer anywhere in their code

Can't Dooooo.... It seem like this is already backported (commit is empty).I won't do anything. MrMeeseeks out.

@krassowski I noticed 4.2.1 went out last week and this wasn't in it. I believe this was missed when creating the 4.2.x branch prior to moving main to 3.0.x, how should we address this?

Hey @ajbozarth I see the commit on the branch 4.2.x: https://github.com/jupyterlab/jupyterlab/commits/4.2.x/

But indeed it is not listing in the changelog (releaser bug?). Could you check it is fixed in 4.2.1?

[ajbozarth]

Ah sorry, I only checked the changelog. It is there, thanks :)

[fcollonval]

Thanks for quickly checking, we need to update the changelog I guess.
