SQL editor: copy/paste issue on firefox

[Goli4thus]

Bug report

Describe the bug

When using firefox (108.0.1) and being within the SQL editor in studio, copying text from one snippet to another snippet deletes text content and creates strange text indenting.

To Reproduce

1. Login to studio using firefox (tested with version 108.0.1)
2. Create the "User Management Starter" snippet via the "welcome / quick start" page
3. Create a new empty snippet
4. Copy all the text from "User Management Starter" (ctrl+a, ctrl+c / or context menu "copy")
5. Paste it (ctrl+v / or context menu "paste") into the empty snippet

The result is:

• compared to chromium (109.0.5414.74) there's a strange delay before text ends up being pasted
• the text is missing various lines
• the text has some strange indention going on (see screenshot)

Expected behavior

The expected behaviour would be that the copied text gets pasted "as is" into the empty snippet / into an external text editor.

Screenshots

Desired:

Actual (issue):

System information

• OS: Manjaro Linux
• Browser: firefox (108.0.1)

Additional context

Judging by the fact that when pasting to an external text editor (GVIM, mousepad) the text content gets "partially deleted" the same way, but the indention isn't "progressively increased" (see scrennshot), one can assume that there's an issue with both the 'copy' and the 'paste' action within the SQL editor.
Within chromium (109.0.5414.74) it works just fine.
