Shared scrolled composite had problem with unecessary horizontal bar displaying (bug 294868) as you can see in unnecessary_hscroll.png.

Fixing this problem (available width is reduced by vertical scroll bar width) caused this bug - shared scrolled composite performs unnecessary wrapping or wraps too soon (pictures should_not_wrap.png and wraps_too_soon.png). This problem can be reproduced in help view, but more obvious it is in attached plugin (viewer with wrap layout).

Maybe the term "wraps too soon" is not correct. It means that text/control is
wrapped before its end reaches the right border of the client area. The text/controls are wrapped like the vertical bar were there (but the vertical bar is not). Also this case (wraps too soon) is unnecessary wrap. This case happens when no vertical and horizontal scroll bar is needed, available height below control/text is lower than the last control/row text height and the last control/text should be from the right border of the client area closer than vertical scroll bar width (quite difficult to write, but see pictures).

This bug hasn't had any activity in quite some time. Maybe the problem got
resolved, was a duplicate of something else, or became less pressing for some
reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it.
The information can be, for example, that the problem still occurs, that you
still want the feature, that more information is needed, or that the bug is
(for whatever reason) no longer relevant.

If the bug is still relevant, please remove the stalebug whiteboard tag.
