Nested Splitpane widths incorrect after upgrading to 2026.09

Questions

Hi all,

After upgrading to 2026.9.0.4202 (servoyextra 2026.9.0), nested Splitpanes initialize with incorrect widths.

At zoom 100%, the inner Splitpane measures the full outer width of 1720 px instead of its available 1290 px, making the left pane too wide and clipping the right pane.

Runtime tracing shows svyOnInit/svyOnChanges running during the first ngOnChanges, before the outer BGSplitter assigns its pane classes. Temporarily deferring these callbacks to ngAfterViewInit restores the correct layout; reloading reproduces the issue.

Could you check this lifecycle compatibility issue? Our form settings are unchanged.

Thanks!
