VSCode mouse middle button deletes the selected text if any

Question

Issue

1. Have some text selected/highlighted, then press the middle button on a mouse (/TrackPoint. I confirmed this issue occurs with both a mouse and a TrackPoint). By "middle" button, I mean the button or the wheel that lets you scroll on an operating system level.
2. The selected text gets deleted.

Environment

• I've been aware of this issue only on VSCode so far. E.g. on GMail editor this behavior is not seen.
• Ubuntu 22.04

Related but different issues

• askubuntu.com#4507 is discussing disabling the "paste" feature. I've disabled it by applying the solution in https://askubuntu.com/a/1144039/24203
• stackoverflow.com#55394404 is discussing about enabling scrolling by middle button on VSCode. Without doing anything particular, I am already achieving that.

Things that are tried but no effect

• Changing some Gnome (i.e. OS-level) settings are false already.

  $ gsettings get org.gnome.desktop.peripherals.mouse middle-click-emulation
  false
  $ gsettings get org.gnome.desktop.peripherals.touchpad middle-click-emulation
  false
  $ gsettings get org.gnome.desktop.peripherals.trackball middle-click-emulation
  false
