New Rule On This?

[TexBlue]

I was talking to a coach today and he gave me a situation that I thought was pretty straightforward until he told me he was given a different opinion by a UIC from Keller.

ASA. The batter hits a grounder to the first baseman. She bobbles it, and then trips going to first. In her haste to beat the BR, she drops the ball, picks it up in her bare hand and then touches first with her glove, before the BR gets to the base.

I told him I would have called the BR out, under these described circumstances. He then told me that the UIC told him this was a greatly debated topic and the Rules Committee came up with an result of safe on this play. Is this true? If so, what is the logic behind the decision? I know I'm probably overlooking it, but the only rule even close to this, that I can find, is 8-7-C talking about a force out on a runner.
