How to reproduce:
1. Create and open a new URP project
2. Create and open a new Shadergraph file
3. Maximize the window
4. Resize the Blackboard to maximum vertically
5. Unmaximize the window
6. Observe the Shadergraph window

Expected result: Blackboard size updates and changes its maximum height to fit in the window upon the resize event
Actual result: Either the top or the bottom of the Blackboard is not visible until it or the Shadergraph window is manually resized

Reproducible in: 2023.1.0a1, 6000.0.55f1, 6000.1.15f1, 6000.2.0f1, 6000.3.0a4

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- The window doesn’t have to be maximized or unmaximized; if the window is resized to a smaller size, the issue will reproduce
- After reproduction, the Blackboard can be moved downward, outside of the view, where it will not be accessible anymore (unless the window is resized to a bigger height or is maximized). And if the window is resized after moving it downward, at some point, the blackboard will not be accessible anymore, until the Shadergraph is reopened
