Git commit f8b4aadf1b79b983fe00b9c5f6dea296b80c6027 by Christoph Wolk. Committed on 19/12/2025 at 22:25. Pushed by cwo into branch 'master'. layouts/FormLayout: avoid binding loop during initial load FormLayout tracks the implicit width in wide mode in a separate property and uses this to decide which mode to use. When the implicitWidth changes, this property is updated with a 0-ms timer, i.e. when the event loop is clear. This generally prevents a binding loop. But during a relayout, the update happens immediately, and then can cause a binding loop, in particular during initialization of the page as at this point the sizing can widely vary, and the component flips between wide and narrow mode as contents are added and the available size of the layout itself is determined. In this case, it may (and usually does) happen that the component thinks wide mode should be off, some change triggers a reevluation of the binding, it's changed to on, the wideModeImplicitWidth is updated and the binding may be reevaluated again while it's still in the process of finishing up the previous one, which triggers the binding loop detection. Instead, we make relayouting also use the timer, rather than immediately triggering its effect. This avoids the loop. We also trigger it explicitly in Component.onCompleted as the test (and potentially other things) expects it to be match after that.
