885344 - Propagate newMessages-true property to parent folder node, if node is collapsed/invisible

Status: RESOLVED DUPLICATE of bug 763534

(Thunderbird :: Folder and Message Lists, defect)

Description

[Ulf Zibis]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release)
Build ID: 20130512194445

Steps to reproduce:

- Folder tree:
  Folder1
  +- Folder2
- have new messages in Folder2


Actual results:

- if Folder1 is expanded/visible, new-mails indication of Folder2 works fine
- if Folder1 is collapsed, there is no indication for new mails in Folder2


Expected results:

If Folder1 is collapsed, newMessages-true property should be set (propagated from Folder2), to make e.g. following userChrome.css coloring the text label of Folder1:
treechildren::-moz-tree-cell-text(folderNameCol, newMessages-true) {
    color: blue !important;
}

The "unread mails"-status is propagated the parent folder, if collapsed. This currently does not happen for the "new mails"-status. IMO this is at least *inconsistent*.

(not related to remembering collapsed state)
