If by "after" you mean "logically after", then pressing backspace will delete b. Then the test really begins: will the >s flip to <s as they should, or won't they. The fact that for you the b did not get deleted by the backspace means that you did not put the caret logically after b, and the results you got are not relevant to the bug.

Whether a browser displays a caret that is logically after the b in the test case to the left of the b or to the right of the b is a separate issue. In Chrome, it it happens to be displayed to the left of the b. If you achieve that (by clicking to the left of the b), then a backspace indeed deletes the b and all the >s flip to <s and the test passes.
