Cannot use "disable for one statement" on test argument lines

[gohierf]

Apparently disabler robotidy: off does not work when applied on keyword arguments line. Here I tried to compensate for RenameVariable which misbehaving with the number variable ${1E-09} used as a default value for argument ${b}.

I tried to disable robotidy in different locations, but it always changes the argument default value.

BEFORE

My Keyword  # robotidy: off
    # robotidy: off
    [Arguments]    ${a}=${{1E-09}}    ${b}=${1E-09}    # robotidy: off
    Log To Console     ${a}
    Log To Console         ${b}

AFTER

My Keyword  # robotidy: off
    # robotidy: off
    [Arguments]    ${a}=${{1E-09}}    ${b}=${1_E-09}    # robotidy: off
    Log To Console     ${a}
    Log To Console         ${b}

The only way to fix it is to put the disabler before the test case, like so.

# robotidy: off

My Keyword
    [Arguments]    ${a}=${{1E-09}}    ${b}=${1E-09}
    Log To Console     ${a}
    Log To Console         ${b}

But then it does not seem possible to reactivate robotidy for the inside of the test case

Side note:
if I run robotidy multiple times on the following code, the line Log To Console ${b} eventually gets transformed.
But not on the two first pass, while ${1_E-09} gets transformed on the first run.

My Keyword  # robotidy: off
    # robotidy: off
    [Arguments]    ${a}=${{1E-09}}    ${b}=${1_E-09}    # robotidy: off
    Log To Console     ${a}
    Log To Console         ${b}

I'm going over old threads. I have tried to reproduce it with new robocop:

*** Keywords ***
My Keyword  # robocop: fmt: off
    # robocop: fmt: off
    [Arguments]    ${a}=${{1E-09}}    ${b}=${1E-09}    # robocop: fmt: off
    Log To Console     ${a}
    Log To Console         ${b}

It is not formatted though. With disabler only with args:

*** Keywords ***
My Keyword
    [Arguments]    ${a}=${{1E-09}}    ${b}=${1E-09}    # robocop: fmt: off
    Log To Console     ${a}
    Log To Console         ${b}

It is also not formatted (except extra spaces in Log To Console).

Can you try if you can reproduce it now?
