Template syntax and directive values formatting not working

[diskdance]

For instance, I have this following code in a SFC

<span :class="['class1','class2',{'class3':!modelValue}]">{{
      $i18n('i18n-key')}}</span>

After formatting the SFC, I expect it to be

<span :class="['class1', 'class2', { 'class3': !modelValue }]">{{
      $i18n('i18n-key') }}</span>

In previous versions of Volar, formatting worked without problems. However, in recent versions (replicated in v1.0.8), this no longer works.
