Important Notes

A prioritized-coordinates approach is used to adjust panning goals based on screen space:

• Fitting the input area is highest-priority.
• If possible, the whole component panel area will be fit.
• If possible, the visualization preview will be fit.
• If there's extra room, margins will be included; the top and left are prioritized because those margins prevent overlap with fixed UI elements.

Checklist

Please ensure that the following checklist has been satisfied before submitting the PR:

• The documentation has been updated, if necessary.
• Screenshots/screencasts have been attached, if there are any visual changes. For interactive or animated visual changes, a screencast is preferred.
• All code follows the
  Scala,
  Java,
  and
  Rust
  style guides. In case you are using a language not listed above, follow the Rust style guide.
• All code has been tested:
  • Unit tests have been written where possible.
  • If GUI codebase was changed, the GUI was tested when built using ./run ide build.

If possible, please add an e2e test (or extend existing "different ways of opening CB") to check if we pan when opening CB near corner. Or a case where we select a node, pan scene so the node is not visible, and press enter, and see if we eventually see CB (we'd probably need to suppress "autoscrolling page" in the check).
