Tab now expands snippet, even when the autocomplete is not visible?



I’ve updated to atom 1.15.0, and I’m puzzled about some new behaviour of atom I’ve just noticed. I’m sure it didn’t do this before:

In the above, I type “html5templ”, then hit <tab> to expand the snippet (expected behaviour). Then I type some test text. Next, I type “form”, then press <escape>, and then I try to press tab, but it expands my snippet instead of performing tthe normal tab function, even though the autocomplete box has disappeared.

Is this the new normal? How would I enter a literal tab character in this situation if I wanted one?
