Submit button with value not included in GET request

[Hwiet]

I should get to creating tiny project to show the behavior, but I've noticed that the value of a submit button is not included when a form is marked with hx-get. Has anyone also ran into this issue?

I expected the value of the button (name=offset in this example) to be included when I have a form like this, but it is not included in the HTMX request. If I change this to a plain form with method=get, the offset parameter is included as a query parameter.

<form hx-get="Chart" hx-trigger="change">
    <button type="submit" name="offset" value="-1">
        Previous
    </button>
 
    <!-- some stuff with more fields -->

    <button type="submit" name="offset" value="1">
        Next
    </button>
</form>

I've written the above form like below to work around the value of the button not being included, but obviously there is more duplication.

<form hx-get="Chart" hx-trigger="change">
    <button hx-get="Chart" hx-include="closest form" hx-vals='{ "offset": -1 }'>
        Previous
    </button>

    <!-- some stuff with more fields -->

    <button hx-get="Chart" hx-include="closest form" hx-vals='{ "offset": 1 }'>
        Next
    </button>
</form>
