When there is a difference between the tags, both pages are displayed at the same time and then a glitch is produced.
On transition with difference (by scoped style):
<div id="__nuxt">
<div class="container" data-v-edeb123a class="page-leave-active page-leave-to">
Page A
</div>
<div class="container" data-v-qazw987c >
Page B
</div>
</div>
On transition with no difference:
<div id="__nuxt">
<div class="container" class="page-leave-active page-leave-to">
Page A to page B
</div>
</div>
