Calling goto_help on same object multiple times throws error

[fthycl]

Tested versions

• Reproducible on 4.3 dev6
• 4.2 does not have the issue

System information

Godot v4.3 (dev6) - Ubuntu 22.04.4 LTS 22.04 - Wayland - Vulkan (Mobile) - integrated Intel(R) Graphics (ADL GT2) () - 12th Gen Intel(R) Core(TM) i7-1260P (16 Threads)

Issue description

When I press F1, and search, e.g., create_convex_collision, more than once, it throws the following error:

Signal 'draw' is already connected to given callable 'RichTextLabel::scroll_to_paragraph' in that object.

Sometimes, it takes more than 2 times to trigger the error.

This is also occurring when show_native_symbol_in_editor lsp method is called multiple times with the same symbol id, since it also ends up calling goto_help.

Steps to reproduce

In v4.3, open the help menu, and search for the same function repeatedly until you get the error in the output.

I noticed this when I was working on improving help tooltips. This happens under certain conditions if the page is already open in the editor.

Sounds like a regression from: #90035.
