I don't exactly know if the folowing problem is with the plugin but since that is where it presents itself here goes:
I load a KML file with markers that have infobubbles. When doing so in WP+plugin the line spacing is high and even marker name and three rows make it flow over the bubble.
If I load the exact same KML with a php file producing the same code outside WP+plugin the rows are closer together. The bubble could hold five rows without overflow.
The bubble html contains only
<br> tags and no
<p> tags yet in WP+plugin they seem to get converted. I even tested disabling the wpautop function but that had no effect.
