Description
Originally by @Artur-
A TreeTable with icons can cause a vertical scrollbar to appear when there are only a few items because the body height is calculated incorrectly. This only seems to happen when the cache is empty and is possibly caused by Internet Explorer putting large image placeholders where the icons should be. Row height is then measured with these placeholders in place and not updated when the icons have been loaded.

Research direction
Start by locating the TreeTable body-height calculation and reproduce the issue in Internet Explorer with icons and an empty cache. Confirm that row height is recalculated after the icons load; done means a TreeTable with only a few icon-bearing items no longer shows an erroneous vertical scrollbar.
