Some background:

The built-in "text" element only draws the text, it doesn't
erase the background first.  If this element is used in
a conventional Labelframe layout, the labelframe's border
will be drawn through the middle of the text.  Tile defines
a specialized version of the element, "Labelframe.text", that
fills the element's parcel with the -background color before
drawing the text.

What's probably happening in TileQt: it looks like
[tile::theme::tileqt::setPalette] only changes Qt's
system colors, it doesn't update Tile's style settings.
So the Labelframe.text widget picks up the original
setting for -background.  To fix this, it should suffice
to just use:

    style configure TLabelframe -background [currentThemeColour -background]

after [tile::theme::tileqt::setPalette].
