…≥] pairs Test Plan: Confirmed that the `edited` handler is now called on swap (pressing "=" when < or > is left of cursor, or deleting when ≤ or ≥ is left of cursor).
Test Plan: Created a fraction without getting a JS error.
Test Plan: Successfully insert ≠ by pasting \ne.
Not sure if this is the best way to do this - KaTeX seems to somehow use just the file name and has it resolve correctly. Suggestions appreciated! Test Plan: See fonts render correctly in webapp Auditors: jack
Test Plan: Make subrepo, see built files present without having to build.
… behavior. Summary: Previously, if you included '-' in `MathQuill.addCharsThatBreakOutOfSupSub()` it would prevent you from being able to enter negative exponents. This is a shame because the behavior is otherwise desirable - at all other times, you want to break out of a super/subscript by default when encountering subtraction that isn't wrapped in parentheses. This fixes the behavior by always allowing a (single) negative sign to be inserted as the first character inside a super/subscript. Addresses some of T2730 Test Plan: In Perseus' MathInput, verified the following: 1) Typing 'x^a-b' results in (x^a) - b 2) Typing 'x^-a-b' results in (x^-a) - b 3) Typing 'x^a', moving left once, then typing '-' results in (x^-a) Reviewers: alpert Reviewed By: alpert Subscribers: michelle, jack Differential Revision: http://phabricator.khanacademy.org/D11366

Summary: Mathquill keeps track of a boolean `shouldBeSelected` based on the input to a `select` method, which determines if the textarea _should_ be selected and, if it isn't, reselects it. There is a bug where one can select the text in the box, continue typing, and not be able to escape with the tab key. This is because the combination of selecting all text and immediately typing does not reset the `shouldBeSelected` variable as it should. Instead, this variable only updates if the user selects the contents and hits "backspace." The fix for this was simple, we need to invoke `selectionChanged()` not only when the selection is deleted, but when it is replaced. Test Plan: I did the following in Perseus (thanks @aria for providing the repro steps) . Create two expression inputs . In the first, type something . Select all (Ctrl/Cmd-A) . Type again . Hit the tab key . See you are directed to the next expression input as expected Reviewers: emily, aria, john Reviewed By: john Subscribers: john, alex, aria, #a11y Maniphest Tasks: T3686 Differential Revision: https://phabricator.khanacademy.org/D16962
