It I understand you correctly (what does `jams' mean?), this is nothing to 
do with resizing. The axis labelling code checks for enough width-wise 
space for labels, but not for enough height-wise space. Specifically, 
do_axis for the y axis contains

 			    /* Check room for perpendicular labels. */
 			    if (Rf_gpptr(dd)->las == 1 ||
 				Rf_gpptr(dd)->las == 2 ||
 				tnew - tlast >= gap) {

so y-axis labels are always plotted for las %in% c(1,2) and hence may 
overlap.  (Similar code exists for an x-axis.)
