Description

Affected: WDialog::positionAt(WWidget*, Orientation) of Wt 4.13.0 (and most likely former versions)
WDialog::positionAt(WWidget*, Orientation) shows and positions the dialog.
Every setMinimumSize moves the dialog to some top-left position and often changes the size improperly (smaller than the specified minimum size).
Another call to WDialog::positionAt(WWidget*, Orientation) repairs it. But it causes flicker and the need to store the WWidget* and Orientation.
This happens regardless of whether the minimum size has actually changed or not.
The dialog did always fit to the viewport, i.e. this also not a reason for moving it.

STR:

run attached main.cpp
select a WTableView cell
press Space (invokes WDialog::positionAt(WWidget*, Orientation))
--> A WDialog pops up aside the cell.
push button "setMinimumSize of dialog"
--> The popup is moved to more or less weird top-left position in dependency of the WTableView.
