odd template collapsing

I like CLion's code collapsing, but it sometimes gives strange results.

For example, this:

template <typename T, typename = std::enable_if_t<std::is_integral<T>::value>>
void foo(T n) {
// process n
}

looks like this when collapsed:

<T,=std::enable_if_t<std::is_integral<T>::value>>
void foo(T n) {
// process n
}
