Using LiveViewTest to assert element with Alpine.js

I’m using both Alpine and LiveView in my project and I’m in the process of writing a test to check if an element has an attribute value of style=display: none;

The particular element has an Alpine directive of x-show attached to it, which should toggle the display.

# page template snippet
<div x-data="{ isShowable: <%= check_showable() %> }">
    <div x-show="isShowable"
       <button>MyButton</button>
    </div>
</div>

What I am finding is that in my test, even when isShowable is evaluated to false, the button does not have style=display: none; attached. I’ve checked this by parsing the rendered HTML using Floki.

However, if I launch my app and inspect my page in a browser, that style is applied.

# test assertion
{:ok, view, _html} = live(conn, "/page")
assert view
       |> element("div[x-show='isShowable'][style='display: none;']")
       |> has_element?()

Wondering if this is expected behaviour when using LiveViewTest and if I am missing something.
