VS code plot pane won't stay splitted

Recently (past week or so), I noticed a change of behavior in how VS Code Julia plot pane displayed figures.

Before it looked like that every time I plotted a new figure

But now when I Shift+Enter inline plot, it produces that

Meaning the right panel opens in full screen over the left panel.

If I try from the REPL, it sometimes (not always and that is weird) keep the split format and sometime display the plot pane in all the screen.

Here are my settings, I use VS Code insider.

VS Code Julia extansion v1.5.6
Julia Version 1.6.3

It might be related to that issue but I did not get how to change the setting to always display the plot in split window without opening the plot in full screen.

Did you try dragging the plot pane into a new editor group manually? IIRC we’ll remember the last column the plot pane was opened in and always try to use that.

Yes I tried that, but at each new plot, it re-opens again as full screen, suppressing the split.
Here is what happen (I just using Plot and do a first plot to avoid compilation time).

Sorry if we don’t see much, I am not expert in screen recording.
