            Bug ID: 509299
           Summary: Inconsistent behaviour with the "Copy Input to"
                    feature with split screen
    Classification: Applications
           Product: konsole
      Version First 25.08.0
       Reported In:
          Platform: Neon

            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: split-view
          Assignee: konsole-devel at kde.org

SUMMARY


STEPS TO REPRODUCE
1. split the window 
2. Select Edit > Copy Input to > All Tabs in Current Window
3. Test issuing some command (for instance `ls -l`). This should be successful
4. Split the screen again and test (eventually successful)
5. Close one of the split screens
6. Split it again
7. Test. This time it will fail
8. Open Edit > Copy Input To and check the settings (it can vary)
9. Repeat a few times to see the different results

OBSERVED RESULT
With the option "Copy Input to all Tabs" enabled: After closing one split
screen and opening (a) new one(s) the asterisk on the right of the tab will be
visible making "copy input" as enabled. When running a command this will most
frequently fail.  Results will vary, though, and some times a few panes will
still receive input, while other don't.

Opening Edit > Copy Input To can show different results, no matter the initial
state. It can have jumped to "None", stay in "Copy to all..." or even in some
cases show _both_ options: "Copy to all..." and "None"(!)

EXPECTED RESULT

When the window is split and the "Copy to all..." enabled, it should copy the
input to all panes. 

If a pane is closed or a new pane is opened, it should inherit this setting or
at least not affect already open ones.

In the case that it were not possible to inherit the setting to new panes, it
should do so consistently by either disbling "copy to all" entirely or leaving
the older panes without change. But the most important issue is that it behaves
consistently and this is documented,
