`#include <fstream>` deleted automatically

[tigerjack]

As per syl20bnr/spacemacs#16501 (comment)

Consider this small example.

#include <fstream>

int main() {
  std::ifstream file("a.txt");
}

When I try to refactor, the include is automatically deleted.

Is there a workaround, i.e. // IWYU pragma: keep (link) or something? This is really annoying, forcing me to turn off the feature entirely.
