PR Summary

configure_subplots requires a) an object from which it can get the
canvas property, and b) somewhere it can store its handle for re-use.

The pseudo-toolbar that is used for most Tool classes is temporary and
does not provide the latter. However, tools inherit from ToolBase
which contains a canvas property and they exist for the lifetime of
the toolbar, so can be used instead.

Fixes #22088

`configure_subplots` requires a) an object from which it can get the

The pseudo-toolbar that is used for most `Tool` classes is temporary and
does not provide the latter. However, tools inherit from `ToolBase`

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

  1. Checkout backport branch and update it.
git checkout v3.5.x
git pull
  1. Cherry pick the first parent branch of the this PR on top of the older branch:
git cherry-pick -x -m1 88faae080b3a4e125e709fc1ac354b170acd4708
  1. You will likely have some merge/cherry-pick conflict here, fix them and commit:
git commit -am 'Backport PR #22743: Fix configure_subplots with tool manager'
  1. Push to a named branch:
git push YOURFORK v3.5.x:auto-backport-of-pr-22743-on-v3.5.x
  1. Create a PR against branch v3.5.x, I would have named this PR:

"Backport PR #22743 on branch v3.5.x (Fix configure_subplots with tool manager)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the Still Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free to suggest an improvement.
