Does "typically" always imply a habitual occurrence?

I suggest you say:

• It was typical of her to panic every time she lost her portfolio.

• Typically, she would panic when she lost her portfolio.

It is the positioning of the adverb that doesn't work in your sentennce.

Typical, meaning: considered to be an example of some undesirable trait: that is typical of you!.

It may describe a personal characteristic so it may refer to a habit or an attitude that tend to happen on a regular basis,

For something to be typical, there has to be a normal or common result that is what is expected. If it had never happened before, than it would hardly by typical..it would be surprising or rare.

So yes, I'd say that there must be a frequent response required for the word to be used...if not habitual.
