[BUG] Copy-paste sequences don't work right in all releases after 8.5.8

Is there an existing issue for this?

• I have searched the existing issues

Description of the Issue

Copy-paste sequence Ctrl+Insert -> Shift+Insert has stop working in all releases after 8.5.8. Its alternative Ctrl+C -> Ctrl+V works right but is less handy in some cases.
It seems that exactly Ctrl+Insert shortcut fails in this sequence as Shift+Insert works fine when there is some data in a clipboard buffer. Moreover sequence Shift+Delete -> Shift+Insert works in all new releases after 8.5.8.

As @alankilborn noted below npp portable version is not affected by this issue.

Steps To Reproduce

1. Use Notepad++ version 8.6 - v8.6.7 (windows x64 or x86 installer version).
2. Open text document and select line of text (I use Ctrl+arrow).
3. Try to copy selected text via Ctrl+Insert shortcut.
4. Try to paste selected text in another place via Shift+Insert shortcut.

Current Behavior

On step 4 Shift+Insert shortcut pastes nothing or some old data copied in clipboard buffer before.

Expected Behavior

Shift+Insert shortcut should paste exactly the text copied on step 3.

Anything else?

No response

Reproduce the Ctrl+Insert → Shift+Insert sequence in the listed installer releases and compare it with the unaffected portable version. Trace how the application handles Ctrl+Insert and clipboard updates; done means the selected text is pasted, rather than old or empty clipboard data, with Shift+Insert.
