clang-format with BlockIndent and ContinuationIndentWidth < 4 not working for if statements

[JoElfner]

Description

When using clang-format v18.0 with the following minimum config:

---
AlignAfterOpenBracket: BlockIndent
IndentWidth: 2
ContinuationIndentWidth: 2
ColumnLimit: 80

Breaking if-statements which are longer than the column limit won't work. I found out, that BlockIndent seems to be broken for if-statements when ContinuationIndentWidth < 4.

Seems to be (slightly) related to: #28052

Input

And I try to format the following if statement:

if ( name== "ABCDE" || name == "ASDASD" || name == "asldmald" || name == "someverylong" || name == "break this" || name == "abcde") {
  callthismethod();
    alsoassignthis = 24;
}

Current output

clang-format correctly formats everything except for breaking the if statement with BlockIndent:

if (name == "ABCDE" || name == "ASDASD" || name == "asldmald" || name == "someverylong" || name == "break this" || name == "abcde") {
  callthismethod();
  alsoassignthis = 24;
}

Expected output:

if (
  name == "ABCDE" || name == "ASDASD" || name == "asldmald" 
  || name == "someverylong" || name == "break this" || name == "abcde"
) {
  callthismethod();
  alsoassignthis = 24;
}

Comment: I don't mind where the || operators go, even though I'd prefer the math-style of breaking before it.

Any way to achieve this?

Related to #79176 which aims for the same formatting, while describing current behavior for ContinuationIndentWidth = 4.
