Error while using tooltips

In IE11 "document.contains" is not supported. Should be replaced with "document.body.contains". Could you please correct this?

Code snippet

In bv-tooltip.js the following code is causing the console error:

    this.$nextTick(() => {
      const target = this.getTarget()
      if (target && document.contains(target)) {
        // Copy the parent's scoped style attribute
        this.scopeId = getScopId(this.$parent)
        // Set up all trigger handlers and listeners
      } else {
        /* istanbul ignore next */
        warn(`${this.templateType} unable to find target element in document`)

Great to hear a fix will be included soon. We use it in one of our projects for which we have a release next week so would be more than great if v2.0.1 can be released this week 😄

I think this bug must have entered back in at some point. I had to manually polyfill to get tooltips working on IE11:

  document.contains = Element.prototype.contains = function contains(node) {
    do {
      if (this === node) return true
    } while ((node = node && node.parentNode))
    return false

@jaeming are you using the latest version of BootstrapVue (v2.1.0)? If so, can you create a new issue?
