self-comparison always evaluates to true in generated code with fluent style

[IronFractal]

Bug Description

When compiling generated code specifically with the fluent style -DSLINT_STYLE="fluent-dark" results in numerous "self-comparison always evaluates to true [-Werror,-Wtautological-compare]" errors
