IE 11 - Not working due to js errors

[Thams]

Hi,
There are JS error occurred in IE11 browser.

1. When tooltip creating.
   Error occurred in ember-tooltip-base.js at line no. 407

Unhandled promise rejection TypeError: Unable to get property 'add' of undefined or null reference

2. When tooltip component destroying.
   Error occurred in ember-tooltip-base.js at line no. 263

Unable to get property 'dispose' of undefined or null reference

@thamsrang IE 11 should support classList just fine. I think these errors may indicate that the target of the tooltip (usually the parent element) doesn't exist by the time it does the setup for the tooltip. are you passing targetId to the tooltip or moving it around the DOM somehow?

[Thams]

@maxfierke Thanks for quick response. I am passing @targetId to <EmberTooltip>.
How to avoid these errors ?

[Max Fierke]

@thamsrang You need to make sure the element specified by targetId exists when the <EmberTooltip> is rendered

[Thams]

@maxfierke What about second error ?

[Max Fierke]

@thamsrang that's probably related to the first error where the tooltip wasn't able to attach itself to the target

Thanks for your comment. Working fine.
