Is this small diameter difference likely to cause a problem in real life?
You bet.

I am trying to put a high angle (130 degree) stem on my road bike to improve the fit and the high angle stems seem to only available for Mountain bars.
Add a layer of cola can as a shim. That generally takes care of the misfit. Make your first ride leaning hard on the hoods along a bumpy run *expecting* the bars to pitch forward and down at any time, and if the bars don't rotate under those conditions, you should be safe. -- Typoes are a feature, not a bug.

Sorry, I don't believe they make negative shims as others have already pointed out. The bars are already bigger than the stem.
Oops, yes, that's correct. Your best bet, then, will be to find a set of 25.4mm drop bars to fit the mtb stem. Although it would be possible to resize the bar clamp to fit the larger diameter, this is a tricky process when the clamp must be honed or machined with a fixed gap retained to ensure that the clamping is successful afterwards. It's been a good many years since I had access to the type of hone that would do this easily, and I'd be hesitant to trust the task to someone unfamiliar with the requirements. Accordingly, the more rational approach is to match the sizes of the components. -- Typoes are a feature, not a bug. Some gardening required to reply via email.

In the "old days" my friend, Bicycle Bob, put a 26.4 Cinelli bar through a 25.4 SR road stem by prying the clamp apart a little. He rode it many hard miles without a problem. Your mileage may vary.
