Hello, I got a strange error if I click on tutorial multiple time, which says Uncaught TypeError: Cannot read property 'setAttribute' of null at IntroJs._showElement (intro.js:1367) at IntroJs._nextStep (intro.js:444) at IntroJs._introForElement (intro.js:270) at IntroJs.start (intro.js:2370).

I know this an relatively old issue, but i have just run into this. The cause seems to be that _onResize blindly tries to refresh, and if the .introjs-tooltip does not exist, it fails. I've worked around this with by adding the following to the function:

function _onResize () { if (document.querySelector('.introjs-tooltip') !== null) { this.refresh.call(this); } }

Hello, I would like to register that I have also just run into this. On my case it happens inside _refresh():

Uncaught TypeError: Cannot read property 'style' of null at IntroJs._placeTooltip (intro.js?479f:603) at IntroJs._refresh (intro.js?479f:493) at IntroJs.refresh (intro.js?479f:2413) at IntroJs._onResize (intro.js?479f:282) at handler (intro.js?479f:1576) (..)

When it calls the following method with null values since the tooltip does not exist: _placeTooltip.call(this, this._introItems[this._currentStep].element, oldtooltipContainer, oldArrowLayer, oldHelperNumberLayer);

Can we please have this fixed in methods _onResize and _refresh?

Thank you veru much.
