The problem appears in version 126.96.36.199 and in revision 1495522. I
attached a one-line patch that fixes it. This problem and the
attached patch are similar to the previously fixed
WW-4115 and its
In method "RefreshModelBeforeResult.beforeResult", the loop over
"root" should break immediately after "needsRefresh" is set to
"false". All the iterations after "needsRefresh" is set to "false" do
not perform any useful work, at best they just set "needsRefresh"
again to "false".
