Tree in scrollview, only the first node is visible?

[alsyia]

Hi,

Thanks for the Textual! It definitely looks like the best TUI library out there, and I'm glad the docs are coming :D

I have a small app with two scroll views containing tree widgets. First widget is instantiated during the on_mount of the app, everything's ok.
The second one, I add in an event handler at app level (the idea is that I want a new tree to appear aside the first one when I click on an element int he first one). The thing is, only the root node of the tree is visible! But if I resize the window (for example), then all the other children nodes appear.
I've tried dozens of variations, and always end up stuck in the same place. Removing the ScrollView fixes it, but I need it since the tree has more nodes than the screen can display.

Am I doing anything wrong?

Thanks!
