Workflow editor toolbar buttons unresponsive when right panel is open

I'm experiencing an issue with the Workflows editor where the bottom toolbar buttons (zoom in, zoom out, pan to center, auto layout) stop responding in certain conditions.

Steps to reproduce:
1. Open Workflows in CDF
2. Create or edit a workflow
3. Open the right panel (e.g., click on a task/agent to configure it)
4. Try clicking the zoom in/out/pan buttons in the bottom toolbar
5. Observe: Buttons don't respond when right panel is close to the left toolbar
6. Maximize browser window or close right panel → buttons work again

Expected: Toolbar buttons should work regardless of panel positions

Actual: Buttons appear to be blocked, clicks don't register when panels are close together

Workaround: Maximize browser window to create space between panels before using toolbar buttons

Has anyone else experienced this? Is there a better workaround or is this a known issue?
