clang-format: BreakInheritanceList

I would like clang-format to always break the line before the colon in the inheritance list. However, the BreakInheritanceList: BeforeColon/BeforeComma option works as expected provided I have multiple inheritance. Do you know if the expected result can be achieved even in the case of a single inheritance?

The expected result is:

class Derived
     : public Base

What I get:

class Derived: public Base

With multiple inheritance it works as expected:

class Derived
     : public Base1
     , Base2
