Custom signal descriptions are not displayed in Node > Signals tab

Issue description

In-script documentation (##) for signal members is not appearing in the Node tab as expected. Other documentation appears to work correctly in the Inspector tab.

Working example (exported variable):

Non-working example (signal)

I have tried deselecting and reselecting the associated Node, changing between the tabs on the left pane, changing active scripts and even restarting Godot - nothing makes it work. According to the GScript Documentation on Documentation Comments, this should work, right? Or is there something completely obvious that I am missing?

Steps to reproduce

1. In Godot, create a new Node of type Node
2. Attach a new script to this Node, accepting all current defaults
3. In the script editor create a signal called Foo and right above it, create a ## comment for it
4. Also create an @exported integer variable called Bar and also create a ## comment for it
5. Unselect and reselect the Node in the Scene tab to refresh the Inspector and Node tabs
6. Hover over the variable in the Inspector tab and see that the added description is shown correctly
7. Hover over the signal in the Node tab and see that the added description is not shown and "No description." is shown instead

This is an example of the script that could be added:

## This is signal foo!
signal Foo

## This is exported signal bar!
@export var Bar : int = 0

I am still getting this issue in 3.6.4 but upgrading to 3.6.5 seems to have fixed it.
