Description of the Change

This pull request fixes cursor blink animation by toggling blink class on .typed-cursor element.

[anteprimorac]

This PR should fix #291.

[mattboldt]

So the main fix here is the usage of animationIterationCount? That wasn't working on the linked issue? Also, could you renamed the .blink class to something more specific? That's too generic of a name to set globally.

[anteprimorac]

Hi @mattboldt ,
yes, changing animationIterationCount doesn't reset the animation.
.blink is now replaced with .typed-cursor--blink.

Do you want this in separate branch?

[dbkaplun]

Any progress on this? I can confirm that the issue is related to animationIterationCount.

Hi @mattboldt, can you merge this PR?
