Hello, I have some issues with responsiveness when using CSS grid and I put charts on it. Searching further, my problem should be equivalent to charts do not get notified for parent size changes and do get notified only for window size changes.

I found this closed issue #3984 and the last comment mentions to open a new related one. From reading the comments there, the problem was:

there is no way to be notified when an element changes size

Since some time has passed and ResizeObserver is well supported from what I'm checking, I think this is an addressable issue. On this comment of issue #3984 is a proof of principle (or/and workaround) using ResizeObserver and I had already created an example in codepen that demonstrates my issue. Also issue #5396 seems to be related I believe.

In codepen example I do use version 2.34.0 which is the current latest, to remember it instead of putting just latest. I did enable template so anyone can test it with other versions if needed.

Available to provide further details when/if necessary.
