   I reproduced this with the default Select2 theme, so Bootstrap is not required for the open-dropdown case.

   In the current keyboard handler, when the dropdown is open, both Enter and Tab trigger results:select and call preventDefault(). That branch does not check shiftKey, so Shift+Tab selects the highlighted result instead of performing the browser's backward focus navigation.

   Chromium checks with an input before and after the Select2 control:

   Sequence	Single select	Multiple select
   Closed dropdown, Shift+Tab	Previous input receives focus	Previous input receives focus
   Open dropdown, Shift+Tab	Dropdown closes; focus remains on Select2	Highlighted Alpha is selected; focus remains on Select2
   Open dropdown, Escape, then Shift+Tab	Previous input receives focus	Previous input receives focus, no option added

   Escape followed by Shift+Tab is therefore a working keyboard route with the tested default behavior. It is not equivalent to fixing one-keystroke backward navigation. A library change should explicitly decide whether Shift+Tab should close without committing a result and allow native focus movement, while preserving the intended unmodified Tab behavior.

   Does your failure occur only while the dropdown is open, or also when it is closed? I tested single/multiple controls with the current bundle and default theme, not Dueuno's Bootstrap integration.
