[rbran]

Version and Platform (required):

• Binary Ninja Version: 5.1.7347-dev (c5ea5795)
• OS: NixOS
• CPU Architecture: x64

Bug Description:

A plugin call to add_type_library adding a new type library is successful and add the library correctly, but the GUI doesn't update the types tab, not showing the user the nearly added library, giving the impression that an error occur.

The type will show if a new type (like struct) is created and deleted manually on the GUI.

Steps To Reproduce:
Use a plugin that create and add a TypeLibrary, or use the idb_import branch: https://github.com/rbran/binaryninja-api/tree/use-type-library and import a TIL file.

Expected Behavior:
The GUI is expected to show the type library after the add_type_library call is returned.
