1140691 - double-rightclick on unselected sidebar tree item will do double-click action for item selected before.

Status: NEW

(SeaMonkey :: MailNews: General, defect)

Description

[Rainer Bielefeld]

During my tests for "Bug 200921 - left click followed by right click in folder pane is taken as a double click" I found for German Seamonkey 2.33.B1 Build 20150223174142 on German WIN7 64bit, That a quick double-rightclick on a not selected node indeed will do a double click action for the latest selected node.

Steps how to reproduce:
0. Launch Mailnews
2. Collapse all accounts
3. Do a single click on one of the accounts "Account1" so that it 
   becomes higligkted
4. Double-rightclick un an other unselected "Account1"
   Unexpectedly "Account1" will bcome expanded

a) effect also can be observed with selected folder in account and 
   drc on other folder of that account (folder selected first will
   change collapsed/expanded)
b) same effect if you do test with folders in different accounts
c) not a problem with
c1) Browser Bookmarks Sidebar panel
c2) Browser History Sidebar panel

It seems there is a bunch of click reaction issues, I will continue research.
First observation of this one here: <https://bugzilla.mozilla.org/show_bug.cgi?id=200921#c5>

Possibly related to "Bug 200921 - left click followed by right click in folder pane is taken as a double click", but probably not a DUP

d) Also reproducible in Safe Mode without any addon
e) also reproducible with Thunderbird 31.5.0. So this might be a Thunderbird or
   Core or event-handling bug, I am still not familiar with the system for 
    assignment here

There is a type in step 4:
should be "Account", not "Account1"

repeated steps how to reproduce because of some typos in original report:
0. Launch Mailnews
2. Collapse all accounts
3. Do a single click on one of the accounts "Account1" so that it 
   becomes higlighted
4. Double-rightclick un an other unselected "Account2"
   Unexpectedly "Account1" will become expanded

Still  REPRODUCIBLE with unzipped installer of  official en-US SeaMonkey 2.53a1 (NT 6.1; WOW64; rv:56.0) Gecko/20100101 Firefox/56.0 Build 20170706013410  (Default Classic Theme) on German WIN7 64bit (later versions not yet tested)
