While a one paragraph large collapsable inset (containing for example a tabular) could be very wide and trigger horizontal scrolling, the code that makes collapsable insets wide when they contain several paragraphs would actually make them narrower in this case.
Typical example is a wide tabular and a caption in a table float, where horizontal scrolling would not trigger.

It is wrong to assume that direction is left-to-right when no indication exist.
Add a new enum with values LtR, RtL and Auto to be used as argument of
the private text() methods. When direction is Auto, let Qt decide how
the string shall be layed out.
This is reimplementation of 51ee267c. A direct cherry-pick was not possible.
Fixes bug #10169.
When the box has a special width, one should not consider that as a fixed width. Otherwise, due to implementation quirks, the width will be set on screen as 1 inch.
A better solution would be to actually set the width by taking in account the contents width, height ans total height. This is not very difficult, but I do not know whether it would workout well in the work area.
Fixes bug #10048.
