Description

Consider the following example:

https://www.software.hixie.ch/utilities/js/live-dom-viewer/?saved=10771

<!DOCTYPE html>
<body style="display: flex; align-items: baseline;">
  baseline
  <div style="border: solid 3px; display: inline-flex; flex-direction: row; flex-wrap: wrap-reverse; width: 25px;">
    <div style="background: lime;">a</div>
    <div style="background: hotpink; font-size: 30px;">b</div>
    <div style="background: lime;">a</div>
    <div style="background: hotpink; font-size: 30px;">b</div>
  </div>
</body>

Here all implementations will align to the visually "last" flex-line. If we follow the same pattern for "last baseline" it'll mean that we'll align to the visually "first" flex-line (Firefox doesn't seem to align to this baseline however). Is this what we want?

Research direction

Review the linked live DOM example and the CSS Flexbox 1 behavior for flex containers using wrap-reverse and baseline alignment. Determine whether last-baseline alignment should use the visually first flex line, including the differing Firefox behavior. Done means the working-group question is resolved and the relevant specification text is clarified.
