Tree control limitations
In the Display Viewer, mouseover text is displayed only if the tree has focus.
In the Thin Client:

The tree node appearance, such as spacing and fonts, might vary slightly as compared to the
Display Viewer, and also may vary slightly between different browsers.

A tree node cannot expand/collapse by double-clicking on it. The +/- icon must be clicked.

In Internet Explorer, nodes expand/collapse even if the tree
enabledFlag property is unchecked. (However, the tree
actionCommand cannot be invoked).

In Mozilla Firefox, the horizontal scrollbar might appear and disappear after each mouse click in the tree.

In iOS Safari (iPad), if the tree
mouseOverFlag property is checked, a user must click a tree node twice to invoke the tree command. The first click only displays the node mouseover text.

In iOS Safari (iPad), scrollbars will not appear in a tree control. If the tree contains more nodes than are visible, use a two-finger drag gesture inside the tree area to scroll.

In iOS Safari, a click on the +/- icon expands/collapses the node as expected. However, if the
execOnLeafOnlyFlag property is unchecked, the tree command is also executed.
