Selectable gets gradually slower

Selectable gets gradually slower


The behavior I'm seeing is so weird (selectable 1.7.2). When I first
start selecting items (i.e., after page load), the lasso appears
immediately. But (and I've tested this a lot), it gradually gets
slower. After about 100 lasso drags, the delay has gone from an
initial 0.1s to a very noticable 1s. And once an actual selection has
started (the lasso has appeared), there is zero lag.
I'm applying .selectable to a table, with a filter of "> tbody > tr".
Some of the TRs have nested tables, if that makes a difference.
Any guesses? Or any news when the refactored selectables will be
nearing completion?
big thanks.
