Spline Component Spline Generation Panel does not trigger Construction Script

Spline generation tool no longer triggers the construction script
We recently updated from Unreal 5.3 to 5.4 and our level designers are having an issue with the spline mesh generation.

Essentially the construction script is not called until the spline mesh is moved.

Even though we were on 5.4.3 we initially assumed this was related to the bug [Link Removed], however we asked the designers to confirm with the standard public release of UE 5.4.4 and they confirmed the issue is still occurring for them.

1. Make a blueprint with a spline attached (e.g., using the modeling mode's draw spline tool, with output mode 'create blueprint' and choose BP_SplineMesh1)
2. Click the spline control points and move them around
Expected result: the blueprint construction script is re-run with the updated spline (during the drag, unless the blueprint class settings option to run construction script on drag is disabled, in which case it should update on mouse release)
Actual result: the blueprint construction script isn't re-run until the user manually switches the selection back to the blueprint actor and moves that.
