Non standard cut/copy paste behavior in thea based editors.

[Phoenixxl]

Bug Description:

An issue is still the non standard cut behavior compared to all other editors.

Steps to Reproduce:

Disable the option of cutting/copying the current line. ( editor: empty selection clipboard -> uncheck Controls whether copying without a selection copies the current line.)

In this mode:

Expected, "normal" behaviour ->
Selecting a piece of text "abc", copying it to clipboard , pasting it, pastes copied text "abc".
Selecting nothing. pressing the cut or copy shortcut while there is no selection, pasting , pastes the content of the clipboard which is still "abc".

Behavior seen in all thea based editors ->
Selecting a piece of text "abc", copying it to clipboard , pasting it, pastes copied text "abc".
Selecting nothing. pressing the cut or copy shortcut while there is no selection, pasting , pastes the content of the clipboard which is still nothing.

When cutting or copying nothing a clipboard stays in it's current state it doesn't get emptied. In thea based editors it gets emptied.
