Subject: LP#1831781: tweaks to eg-help-popover
X-Git-Url: http://git.equinoxoli.org/?p=evergreen-equinox.git;a=commitdiff_plain;h=a1a03fa71d95bed03a5498d12c3be8c5f0ec10cf

LP#1831781: tweaks to eg-help-popover

- Wrap the image in a button; this removes the need for setting
  tabindex and makes the cursor display as a pointer when it
  is over the popover.
- Add aria-label attributes
- add some usage comments

Thanks to Jane Sandberg for the feedback that inspired this patch.
