Popout widget then setWidgetState(WidgetState.Hidden)

[a-gagnon]

Describe the bug While testing the fixes in #524 , I noticed that my widget does not get re-rendered when going into popout mode. Because of that, the following line does not get reevaluated, and the close button is displayed:

const showCloseButton = (true !== UiFramework.frontstages.activeFrontstageDef?.isPopoutWidget(widgetId));

The associated code to closing the widget is this:

const widget = UiFramework.frontstages.activeFrontstageDef?.findWidgetDef(id);
widget?.setWidgetState(WidgetState.Hidden);

We hide the close button when in popout because it looks awkward having two 'X' stacked on top of each other (1 from the window frame and 1 from our UI). If we try to click on it while in a popout, we end up getting the infinite resize observer as discussed in #536

To Reproduce Steps to reproduce the behavior:

1. Create a widget
2. Popout widget
3. Call setWidgetState(WidgetState.Hide) while in popout

Expected behavior Not sure what it should do, but that has to be predictable.

1. There is indeed no public event that I can see that would allow you to know that a widget was poped out, this could be an initial API to put in a hook as asked in #554
2. Can you confirm if you normally close the widget (by closing the popout widget, NOT with the SetState) you get the expected behavior/No ResizeObserver issue ? If it's the case, that should help pinpoint the behavior difference on our side.

Correct, if I close the popout, it brings my widget back to the panel where it was initially and I don't see the ResizeObserver warning.

Hi @a-gagnon, 4.7.2 was released today and revert the change to the reparenting, this issue should be no longer be present. We will find a different solution to the initial issue. Let me know if we should close this issue.
