The original `builtins.getContext` test from1d757292d0would have caught this. The problem is thatb30be6b450adding `builtins.appendContext` modified that test to make it test too much at once, rather than adding a separate test. We now have isolated tests for both functions, and also a property test showing everything put together (in the form of an eta rule for strings with context). This is better coverage and properly reproduces the bug.
