Fix #6618: RTL (sub)*section after LTR text doesn't compile.

When deciding whether to switch encoding or not, the "fragileness" of
the enclosing environment (rather than that of the actual one) should
be taken into account, as we already account for the current "fragility"
by outputting the encoding switch just before switching environment.
