System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 511.79

Blender Version
Broken: Current main.
Worked: Never.

Short description of error
When a node has hidden sockets and is selected, hovering over a dropdown within that node and then performing the Toggle Hidden Node Sockets hotkey can cause one of the node's input/output sockets to briefly appear as a dropdown as well. The socket returns to normal when the mouse moves again. However, clicking before doing so will cause Blender to crash to desktop. This appears to happen in all node editors, with any node or node group that contains one or more dropdowns.

Example of output socket appearing as dropdown, then returning to normal when the mouse moves:

Same, but with a different dropdown that causes an input socket to be affected:

Exact steps for others to reproduce the error

Open dropdown_hover.blend
In the geometry nodes editor, select the node group
Place the mouse cursor onto the dropdown button next to the NodeGroup property
Press the Toggle Hidden Node Sockets hotkey (Ctrl+H by default)
Five output sockets are now shown, the second of which appearing as a dropdown
Without moving the mouse, press the left mouse button to crash Blender
(Optional) Repeat the above steps for other dropdowns within the node group or in the Switch and Image Texture nodes

Additional information
The socket that gets affected (if any) seems to be determined by the order and position of each of the node's dropdowns and sockets before and after the hidden sockets appear. On the left, the dropdown at index 6 is being hovered over. On the right, after showing all hidden sockets, the input socket that now appears at that same index is affected:
