Summary

Changing the Shape type of an existing shape (e.g. Rectangle → Ellipse)
in the Properties panel does not propagate to other clients viewing the same
board in real time. The other client keeps rendering the previous shape type
until the page is reloaded.

Steps to reproduce

Open a board in tab A.
Open the same board in tab B via the shared link.
Confirm both tabs are connected (cursor presence is visible).
In tab A, draw a Rectangle.
In tab A, select the rectangle and change Stroke color via the
Properties panel — observe that tab B updates immediately.
In tab A, with the same shape selected, change Shape from Rectangle
to Ellipse (or any other shape type) in the Properties panel.

Expected

Tab B updates the rendered shape to an Ellipse in real time, the same way
it received the stroke/fill color changes.

Actual

Tab A: shape becomes an Ellipse immediately.
Tab B: shape stays as a Rectangle indefinitely. It only changes to the
Ellipse after manually reloading tab B.

## Summary Changing the **Shape** type of an existing shape (e.g. Rectangle → Ellipse) in the Properties panel does not propagate to other clients viewing the same board in real time. The other client keeps rendering the previous shape type until the page is reloaded. ## Steps to reproduce 1. Open a board in tab A. 2. Open the same board in tab B via the shared link. 3. Confirm both tabs are connected (cursor presence is visible). 4. In tab A, draw a Rectangle. 5. In tab A, select the rectangle and change `Stroke` color via the Properties panel — observe that tab B updates immediately. 6. In tab A, with the same shape selected, change `Shape` from `Rectangle` to `Ellipse` (or any other shape type) in the Properties panel. ## Expected Tab B updates the rendered shape to an Ellipse in real time, the same way it received the stroke/fill color changes. ## Actual - Tab A: shape becomes an Ellipse immediately. - Tab B: shape stays as a Rectangle indefinitely. It only changes to the Ellipse after manually reloading tab B.
