C++ guide: 'else if constexpr' fails with readability/braces

"If/else bodies with multiple statements require braces [readability/braces] " error is given for code like

if constexpr (foo) {
...
} else if constexpr (bar) {
...
} else {
...
}
while

if (foo) {
...
} else if (bar) {
...
} else {
...
}
is fine.
