New Context Pad is not repositioned on Properties panel move

[marstamm]

Describe the bug

The Context pad is automatically repositioned when I move the canvas. When I expand the properties panel instead, to context pad can be (partially) hidden and is repositioned/removed when I hover over the canvas

Steps to reproduce

1. Open Modeler with --enable-new-context-pad
2. Select an element
3. Expand Properties panel over the selected element
4. The properties panel is partially hidden

Expected behavior

Context pad position position is updated on resize

Environment

• Version: 5.24.0-rc.0
• Operating System: Windows 10 amd64
• Plugins:
• Execution Platform: BPMN - Camunda 7

Additional context

No response

I'd expect a canvas.resized event that the context pad can react to.

Yea. We could use such event to hook up other changes such as the responsive palette, too.

@philippfromme after further investigating this we have most measures in place:

• canvas.viewbox.changed is there to hook into
• Canvas does not offer an API to notifiy it got resized; I'd expet that this would cause re-computation ad notification of interested parties.

Update: Canvas#resized is already there, but not properly hooked up.

I don't know if I understand correctly but Canvas has a resized method which fires a canvas.resized event to the eventBus. The issue can be fixed by listening on it in the contextPad to fire the updatePosition method. However, the contextPad is only positioned after the sizing is done. But it fixes necessary hovering after resizing the propertiesPanel.

@options-a11y My appologies! In fact canvas already has the resize method, and event as you mentioned :tada:.

We just need to ensure we properly hook this up and/or fire canvas.viewbox.changed on canvas.resized.
