CodeAction to insert missing parameters overwrites optional parameter

[JessicaJHee]

Given this Qute template, with required parameter name and optional parameter placeholder

{#input name="task" placeholder="Type task and press ENTER"/}

Applying the code action for the missing parameter class will result in:

{#input name="task" class="class"/}

Expected output:

{#input name="task" placeholder="Type task and press ENTER" class="class"/}
