Use the camelCase version v-model:msgTest as a workaround (will not work in HTML templates, e.g. outside vue files)

It also looks like the modifiers are being passed as attributes (kebab or camel case):

<div id="app" data-v-app=""><h1>testtttt</h1><h2 msgtestmodifiers="[object Object]">beforetestttttafter</h2></div>
