EuiSelectable
I noticed that the changes to the inner content of EuiSelectableListItem made in #5581 really messed with some custom renders like in the sitewide search template:
Before

Originally, the fix was to make it easier to override the truncate/flex nature of the inner list option elements but just removing the extra elements. This wasn't a good fix.
Instead, I've reverted back to the original contents and added an explicit
textWrap = 'truncate' | 'wrap'option to EuiSelectableListItem and inherited this in EuiSelectableList and EuiSelectable.listProps. This immediately fixed the sitewide template:After

EuiSuggest
But it then broke the suggest list item (of course). So in EuiSuggest, I force EuiSuggestItem's own
truncateproperty to betruewhenisVirtualize = trueand set thelistProps.textWrap: isVirtualized ? 'truncate' : 'wrap',.This even fixes the display better for virtualized items by forcing the truncation instead of just cutting off the item:
