That's because the index you gave is the one for the <caption>
element, so inserting text at that location would insert it *before*
the <caption>. You have to add 1 to move after the <caption> start
tag.
To make things clearer (easier to read/maintain, at the expense of
being slightly less performant, according to Dan), you can use Point
static methods, such as Point.start, Point inElement or
Point.textOrElementStart.

Then use getOrderedSelectionRange instead of getSelectionRange, and
then you'll have what you want with getFirst, without the need for a
Math.min (but of course, Math.min also works ;-) )
And if you need points instead of indices, you can use
getOrderedSelectionPoints.
