Performance regression in 0.0.16 (possibly related to bind:clientWidth?)

First of all, great package, I love it! :)
I am using this package to render a chart in a table, and it seems to be having performance issues starting with 0.0.16.
I have created a REPL so that you can test it out. Clicking on refresh should give you some number, which is a rough and inaccurate estimate of the time it took.
Now, run the same thing, but using 0.0.16
. You can see it's about 2-3 times slower in the best cases.
When observing performance in the profiler, it seems to be related to style and layout recalculation.
0.0.15:
0.0.16:
Also, I noticed that some purple appeared during mount (which is what is causing major issues in my website):
0.0.15:
0.0.16
This looks pretty much like layout thrashing caused by bind:clientWidth
and bind:clientHeight
, but I could be wrong here.
I'm guessing this is a Svelte issue, but I'm wondering if we could do a quick fix in Pancake to bring back the original performance here
