Is `this.$refs.vsl.getSize(currentSid)` got `undefined`?

Do you mean a table like that ? 

Maybe but not soon.

Of course!

At the end of the year, the work is very busy 😂

> but its not triggered if list was filtered That looks like a bug. Can you describe it or give an example

These events are both necessary inside component, is there make performance problems or stuck?

One of the problems I found before is that when Chrome Devtool is turned on, it will get stuck. When Chrome Devtool is turned off, it will be OK.

Actualy you can't keep scroll position stay where it was before rendering new contents to head. The way you can do is scrollTo an offset which is the addition items...

`vsl.getSize()` base on `ResizeObserver` api, does your browser not support it?
