protected int getButtonHeight(CubaButtonWidget widget) {

    if (captionElement == null) {
        return getWidgetHeight(widget);
    }
    // The LinkButton component has an ability to wrap caption onto multiple rows.
    // Thus, at the first recalculation of the heights for the slots, the "getWidgetHeight()" call
    // returns an invalid multiline component height.
    // In order to calculate the really required caption height, regardless of the 'white-space' mode,
    // we need to explicitly set it to 'nowrap'. After calculation, it's reverted back.
    Style style = captionElement.getStyle();
    String prevWhiteSpace = style.getWhiteSpace();
    style.setWhiteSpace(Style.WhiteSpace.NOWRAP);
    int buttonHeight = element.getOffsetHeight();

    if (prevWhiteSpace != null && !prevWhiteSpace.isEmpty()) {
        style.setWhiteSpace(Style.WhiteSpace.valueOf(prevWhiteSpace));
    } else {

        // a slot has no Caption at first iteration of 'maxCaptionWidth' calculation,
        // as the result, for the second and so forth iterations, when the rest of
        // components get their captions, 'caption.getRenderedWidth()' returns an incorrect value.
        // In order to calculate the really required caption width, regardless of the 'white-space' mode,
        // we need to explicitly set it to 'nowrap'. After calculation, it's reverted back.
