[EuiAccordion] Doesn't adjust exposed height when content height changes

[cchaos]

This usually happens the parent's width changes forcing the content to reflow and increase/decrease in height.

The EuiAccordion component should watch for changes in the children's size and auto-adjust.

EuiAccordion uses EuiMutationObserver, and should be moved over to EuiResizeObserver. Note that there is a related bug in EuiResizeObserver with an open PR #3088, which means simply moving to EuiResizeObserver does not fix this in all browsers yet.

Hi, I'd like to try this!

@winnllam go for it! We'll take a look at a PR, but we do not assign issues out.

In general, once on Github, any issue can be worked on by the community. We sometimes reserve larger projects or ones that are core to our roadmap or design to be done internally. In these cases we mark these issues as assigned to a person using Github. We do not, as a policy, assign issues to community members. If you find an issue that is not assigned, assume that you are welcome to work on it and can submit a pull request. Feel free to leave a comment to mark intent and avoid conflict.

EUI is built primarily by employees of Elastic. We try to do this in the open as much as possible, but do utilize closed meetings and other planning tools to dictate our longer term roadmap. We try to transcribe the decisions from these discussions in the form of specifications to Github issues for transparency. In general, once on Github, any issue can be worked on by the community.
