[Octave-bug-tracker] [bug #57635] Editor often has focus but no cursor until clicking elsewhere and then clicking in editor

[Hg200]

Follow-up Comment #42, bug #57635 (project octave):

The bug disappears if we either remove line file-editor.cc:969 *OR*
file-editor-tab.cc:266. So it looks like there is some interference between
the two proxies as well.

My understanding is that file-editor.cc:969 "resets" the proxy that is
installed into the file_editor_tab_widget, so that the focus is forwarded from
the file_editor_tab_widget widget to the active file_editor_tab widget. In the
file_editor_tab constructor, proxies are installed into each of the
file_editor_tab widgets (line file-editor-tab.cc:266) in order to propagate
the focus further to the m_edit_areas. A proxy chain is allowed by the API.
Remains odd.
