- documentating `textWrap` for now, will also demo `truncationProps` once we add that

+ add logic for conditionally rendering `<EuiHighlight>` if no search is present (removes a `<span>` wrapper and extra logic)

+ add tests

not super sure how useful this is, since it requires virtualization to be off, but I want this API to match the upcoming `truncationProps`

+ configurable at the option level as well

+ bonus grammar/link fix on combobox truncationProps docs

+ fix broken link on combobox page

…vers

- to help analyze downstream component performance

…tion is slightly off

the `width` is correct but canvas's `measureText` API is off very slightly on mount for some very frustrating reason

the best solution/workaround I came up with was adding a configurable tick/wait (and yes, 1 doesn't work either, has to be 2 for EuiSelectable :/)

…cated line

- by using `EuiAutoSizer` and attempting to guesstimate the default available width for options that don't have custom `append` or `prepend` nodes

[cleanup] Move several `options` based vars to state, to more explicitly limit the amount of times they fire/cause rerenders

+ fix `EuiAutoSizer` test mock to fire `onResize` on mount (same behavior as actual prod)

- some tests copied from EuiComboBox, but EuiSelectable also has extra affordances that need to be tested for (resizing etc)
