Only stop if the transition on this element ended

This way it doesn't end when some random element elsewhere on the page has an ending transition.

It must be noted that this is not a complete fix. If you have multiple transitions on the element, it still ends when the first ends.

I ran into this not working (the transition ends almost immediately, because some unrelated transition ends). This fixes it for me, but I was wondering whether this cornercase was considered, and whether the other cornercase (multiple transitions) was considered.

I think it's very hard to get this correct, and think it might be better to make the timeout explicit, or at least allow to set it explicit, and fall back to this behaviour. But I'm really interested in feedback on this one.

The previous wording could be interpreted to mean sub-trees moving from
within one sibling to within another, rather than the shuffling of siblings on
a single level as intended

Improved readability by removing semicolon

The first sentence had an unnecessary semicolon which made the whole thing difficult to read.  The new syntax is not only easier to read but also more exciting.

Fix inconsistency in mockComponent argument name

The second argument of mockComponent was listed as tagName, but referred to in the description as mockTagName. I changed the first one to mockTagName to be consistent.
