<h3 dir="auto">Superset version</h3>
<p dir="auto">0.28.1<br>
This bug did appear somewhere in the past 12 months or so. It's not recent, and is unrelated to the many changes that appeared in 0.28.</p>
<h3 dir="auto">Expected results</h3>
<p dir="auto">There should be only one tooltip instance</p>
<h3 dir="auto">Actual results</h3>
<p dir="auto">Sometimes a tooltip get "stuck". Very similar to bugs that were fixed by <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="204757207" data-permission-text="Title is private" data-url="https://github.com/apache/superset/issues/2096" data-hovercard-type="pull_request" data-hovercard-url="/apache/superset/pull/2096/hovercard" href="https://github.com/apache/superset/pull/2096">#2096</a>.</p>

<h3 dir="auto">Steps to reproduce</h3>
<p dir="auto">I've been unable to find a recipe for consistent reproduction, but the bug happens to me multiple times per day.<br>
Browser: Chrome on a mac.</p>
<p dir="auto">Hi Superset people! I need your wisdom once again. Is it even a Superset issue? Or an nvd3 one?<br>
Is there any chance for a fix or a workaround? Thanks in advance!</p>
