The data editing tab does not open when the breakpoint is active

Issue description

It's hard to explain in words, but I'll try. There is a global script - "Global", which is in the autostart. It has this.

extends Node
var rel_table = [
	[
		{ "sa": 1}
	],
	[0]
]

There is an empty scene with a script attached that has this.

extends Control
func _ready():
	var s = G.rel_table
	print(s)

Put a breakpoint on print(s),
Run the scene, debugger opens, click on Globals->G.
Now we have the data we need opened in the inspector. Click on Members->Rel Table (expand).
Press 0->Array(size 1).
Finally click on 0->Dictionary...

And absolutely nothing. Dictionary tab won't open. That is, the tab tries to open, but it closes immediately.

In action (3.4.4.stable), sometimes it doesn't open at all, sometimes it closes immediately:
