In the Basic IDE, if you place:

Option Compatible
Option ClassModule

At the header of a Basic Module, double clicking method names on this module will stop working in the Object Catalog.

For instance, consider these macros in Module1:

Sub Macro1
	'Dummy Macro
	MsgBox "Dummy 1"
End Sub

Sub Macro2
	'Dummy Macro
	MsgBox "Dummy 2"
End Sub

Sub Macro3
	'Dummy Macro
	MsgBox "Dummy 3"
End Sub

Sub Macro4
	'Dummy Macro
	MsgBox "Dummy 4"
End Sub

If you create them in Module1, it is possible to navigate the macros using the Object Catalog and double-clicking their names will move the cursor to the beginning of the macro definition.

However, after adding "Option ClassModule" at the top of the module and compiling the module, double-clicking will stop working.

System info

Version: 24.2.0.0.alpha1+ (X86_64) / LibreOffice Community
Build ID: 07036eea5089feae511145412d7105cb76c1955a
CPU threads: 16; OS: Linux 6.5; UI render: default; VCL: gtk3

Repro already with 4.2.0 alpha1 on Windows.

- still an issue

on a side note:
if you out-comment "Option ClassModule" and restart libreoffice, navigation will work again. that is, simply closing and re-opening the basic ide is insufficient.
