The default behavior for layout/core AccessibleCaretManager when responding to Javascript / content initiated selection changes is to HideCarets(), which closes the FFOS UtilityBubble and its counterpart, the mobile ActionBarHandler.

When mobile implemented bug 1215959, we extended the logic [0] to attempt backwards compatibility we previous behaviors, for ex: Bug 1096938 

This is currently preffed behind: |layout.accessiblecaret.extendedvisibility|, which is a catch-all for mobile compatibility behaviour: [1], and might be properly broken out into a unique pref, at least until there's a consensus on UI behavior.

For plong-term planning, also keep in mind: Bug 1171110 - Floating text selection action bar for Android M , which will provide mobile with an FFOS-like UtilityBubble

I'm a de facto owner of AccessibleCaret, so I think I can review this patch :-)

If the patch touches other layout code, :roc is the person to ask for review.
