Wt

This was first reported as a comment on issue #11233: https://redmine.emweb.be/issues/11233#note-3

Note: this issue only appears when WBootstrap5Theme is used.

When a dialog with particularly wide contents is created, and a width is set, then the contents may overflow and be hidden:

    dialog->setWidth(800);
    dialog->contents()->addNew<Wt::WText>(
            "This is really long text. This is really long text. This is really long text. "
            "This is really long text. This is really long text. This is really long text. "
            "This is really long text. This is really long text. This is really long text. "
            "This is really long text. This is really long text. This is really long text. "
            "This is really long text."
    );

Additionally, resizing does not work (resize icon is not shown, and we can't drag the corner of the dialog).

See attached screenshot.
