Yes, the problem is that `syntax-ppss` is affected by the current syntax-table yet it doesn't pay attention to syntax-table changes when it comes to enforcing that its cache is not stale. The arguably better way to solve the problem is to not change the syntax-table used inside `syntax-ppss` and `syntax-propertize`. This is especially true for `syntax-propertize` if you use `syntax-ppss` in your `syntax-propertize-function`. The best way to do that is to set `syntax-ppss-table` to the syntax-table that should be used. Stefan
