possible bug with treegrid inside section stack ?

[ayhandalgic]

Dear Support

I have a section stack with containing a treegrid component.
Once I collapse the section with the treegrid, some components of this treegrid still visible along with the new section stack data.

Have a look the screen at the attachment to see this behavior please.

section stack 1 -> treegrid
section stack 2 -> html flow loaded from file

if I replace the html flow with something else, it works as expected
