Input

<template lang="pug">
input#dropzone.image-input(
        @drop.stop.prevent='onDrop($event.dataTransfer.files); dragging = false')
</template>

Output or Error

Expected Output

Should be unchanged

Additional Context

Reproduce the reported formatting with the provided Pug input, Vue template, and Prettier v2.8.3 configuration. Trace the plugin's Pug formatting path and compare the generated output with the unchanged expected input; done means the semicolon between expressions is preserved.
