I have been vuetify's <v-tooltip> and I don't find any attributes in their API so I could either use \n or <br /> to create a newline inside the tooltip template.
Exemple :
<v-tooltip>
<template v-slot:activator="{ on }">
<v-btn>
button
</v-btn>
</template>
<span>First line \n second line</span>
</v-tooltip>
This will still display
First line second line
instead of
First line
second line
Insert p tags instead of spans, this will separate on to two lines.
Added mb-0 to remove excess spacing.

</html>You can just insert <br /> and v-html into your tooltip text and the text will appear in a new line.
Example:
<v-tooltip top transition="fade-transition" open-delay="500">
<template #activator="{ on, attrs }">
...
</template>
<span v-html="getTextWithNewlines"></span>
</v-tooltip>
getTextWithNewlines is a function which returns text with newlines... (<br />).
