When I attach an image diff with Attach keyword, the report comparator has the height of the shortest image

[gt-siberian153]

Hi everybody,

I'm using allure-robotframework==2.15.2 with robotframework==7.3.2
My report is generated with allure-commandline version 2.34.1 npx --yes allure-commandline generate

When I attach images (diff, expected, actual) with Attach keyword, then the images displayed in "Show overlay" mode are too short. The bottom of the biggest images is hidden. I have to set the effective size of the //div[@class="screen-diff__overlay screen-diff__container"] to show it completely.

For example I've two images with different sizes :

• left img 2109px
• right img 1907px
• Comparator size 1926.9px //div[@class="screen-diff__overlay screen-diff__container"]

I expect the comparator height to be at least 2109 instead of 1926

I don't know if the issue is on allure report or in the listener allure-robotframework

Here is my snipet :

    ${dico}=    Create Dictionary    expected=data:image/png;base64,${expected_Base64}
    ...         actual=data:image/png;base64,${actual_Base64}    diff=data:image/png;base64,${diff_Base64}

    ${discoAsString} =    Convert To String    ${dico}
    ${discoAsStringDoubleQuote}    Replace String    ${discoAsString}    '    "
    ${dicoAsJson}    Convert String To Json    ${discoAsStringDoubleQuote}
    AllureLibrary.Attach    ${discoAsStringDoubleQuote}    name=Screenshot diff
    ...                     attachment_type=application/vnd.allure.image.diff

Thanks for feedback
