Fix annotation input focus trap regression in Safari

`setSelectionRange(0, 0)` added in mozilla@44b24fc for mozilla#12359, required only by Firefox ([bug](https://bugzilla.mozilla.org/show_bug.cgi?id=860329)), causes issues mozilla#13191, mozilla#12592 in Safari.
`scrollLeft = 0` is a fix that breaks the focus trap in Safari while **keeping Firefox behavior same for mozilla#12359**.
