EuiInMemoryTable's "Rows per page" won't stay open in Popover

[legrego]

Tested on both 3.0.0 and 3.1.0.

When trying to change the number of results per page, the page size selector apprears for a split-second, then disappears on its own.

Essentially, I have an EuiInMemoryTable defined within an EuiPopover:

<EuiPopover button={button} isOpen={this.state.isOpen} closePopover={this.closePortal} anchorPosition={'rightCenter'}>
  <EuiInMemoryTable
    itemId={"id"}
    items={this.props.spaces}
    columns={this.getColumnConfig()}
    pagination={{
      initialPageSize: 10,
    }}
    search={{
      box: {
        incremental: true
      }
    }}
  />
</EuiPopover>
)

The example above is slightly simplified, but I can post a full sample if needed

This was fixed in #1039, but that fix is unreleased; I'll cut a new release.

Fixed in 3.2.0!
