Add support to
onFocusOnly
option that is available onol/interaction/MouseWheelZoom
and onol/interaction/DragPan
(andol/interaction.defaults
for completeness).For the site I'm developing right now this is a must, since we have lots of scrollable content on a page with a map. Without
onFocusOnly
the map traps the mouse wheel, resulting in a bad user experience.Please note that the
tabindex
thing in<aol-map>
is needed for thefocusWithTabindex
condition to work inside OpenLayers. I don't expect any breaking change in this PR, given that in using[attr.tabindex]
withnull
will effectively not set tabindex (as it occurs before the PR). Also,tabindex
property didn't exist inaol-map
altogether (so nobody should be using it).
