In order to avoid this, some degree of leaning on the front half of the bike is neccessary. This is not a difficult thing to do at all, but it is true we forget this sometime and in return, we get awfully embarrassing moment in public. Ooops.
Here is a japanese guy who takes a radical solution for this. He drilled a couple of new locking holes for front telescopic tube. The holes are 14mm diameter and position 7cm below the default locking holes.
By this modification, the riding position for his A-bike is altered and it allows him to do the leaning more naturally.
His website is in Japanese, but it has a lot of detailed images, so you may not need Babel fish translation to get the idea.

This guy is a dedicated Zero-bike (another tiny folding bicycle) owner, so his website is titled "ZERO BIKER".

Interesting comparison, A-beke and Zero-bike next to each other.
