QToolbarTitle is set to grow to the available space

[gearmobile]

I want to move the menu items to the left, to the title. But I can't. Why?

<template>
  <q-layout>
    <q-layout-header>
      <q-toolbar inverted color="dark">
        <q-toolbar-title>START</q-toolbar-title>
        <q-tabs inverted align="left">
          <q-tab slot="title" name="tab-1">primo</q-tab>
          <q-tab slot="title" name="tab-2">secondo</q-tab>
          <q-tab slot="title" name="tab-3">tetro</q-tab>
        </q-tabs>
      </q-toolbar>
    </q-layout-header>
    <q-page-container>
      <router-view />
    </q-page-container>
  </q-layout>
</template>

QToolbarTitle is set to grow to the available space.
Need to add a prop for QToolbarTitle to be able to disable this behaviour?
