DOMException: Failed to execute 'querySelectorAll' on 'Element': '[id='__dojo__'] [dijitDateValue=1532617918647]' is not a valid selector.

Hello,

It seems that the selectorEngine "lite" isn't well implementated at "dojox/widget/MultiSelectCalendar", currently you have the following code with the uncompatibility:

`

    _setCurrentFocusAttr: function(/*Date*/ date, /*Boolean*/ forceFocus){
        // summary:
        //      If the calendar currently has focus, then focuses specified date,
        //      changing the currently displayed month/year if necessary.
        //      If the calendar doesn't have focus, updates currently
        //      displayed month/year, and sets the cell that will get focus.
        // forceFocus:
        //      If true, will focus() the cell even if calendar itself doesn't have focus

        var oldFocus = this.currentFocus,
            oldCell = oldFocus ? dojo.query("[dijitDateValue=" + oldFocus.valueOf() + "]", this.domNode)[0] : null;

        // round specified value to nearest day (1am to avoid issues when DST shift occurs at midnight, see #8521, #9366)
        date = new this.dateClassObj(date);
        date.setHours(1, 0, 0, 0);

        this._set("currentFocus", date);
        var currentMonth = stamp.toISOString(date).substring(0,7);
        //We only redraw the grid if we're in a new month
        if(currentMonth != this.previousMonth){
            this._populateGrid();
            this.previousMonth = currentMonth;
        }

        // set tabIndex=0 on new cell, and focus it (but only if Calendar itself is focused)
        var newCell = dojo.query("[dijitDateValue='" + date.valueOf() + "']", this.domNode)[0];
        newCell.setAttribute("tabIndex", this.tabIndex);
        if(this._focused || forceFocus){
            newCell.focus();
        }

        // set tabIndex=-1 on old focusable cell
        if(oldCell && oldCell != newCell){
            if(dojo.isWebKit){  // see #11064 about webkit bug
                oldCell.setAttribute("tabIndex", "-1");
            }else{
                    oldCell.removeAttribute("tabIndex");
            }
        }
    },

` I think you need to change the "oldCell" query to:

oldCell = oldFocus ? dojo.query("[dijitDateValue='" + oldFocus.valueOf() + "']", this.domNode)[0] : null;

I'll make a pull request fixing this as soon as someone here accept this is an actual issue... thanks.

Makes sense, that's already how the other dojo.query() call in that method works. (It's curious that you don't need quotes for [foo=bar] but you do need them for [foo=123], but I confirm that it's true by testing document.querySelectorAll() on Chrome.

This was a Google Chrome bug, they fixed it pretty fast, so there was no reason to make a PR.
