FEC-1743 #comment Call load on non-sibling video element #time 1.5d

Due to FEC-1523 the player doesn’t call load before each play.
When first playing an ad on same video tag as our embed player (sibling
not supported on mobile) the load is not called and setting the source
by the 3rd party library doesn’t succeed (for some reason?).
Added a load call for the code path where we use same video tag, before
we call the 3rd party library!
