/**
 * Remove one SPECIFIC evaluation context, wherever it currently sits.
 *
 * The asynchronous evaluation path holds its context across an `await`
 * (`BoxedFunction._computeValueAsync`), so by the time it unwinds, its frame is
 * not necessarily on top: another evaluation on the same engine may have pushed
 * above it. Popping the top there would destroy a frame belonging to something
 * still running — disposing its bindings out from under it. Removing by
 * identity leaves every other frame intact.
 *
 * A no-op if the context is not on the stack (already removed).
