Uncaught TypeError: Cannot read properties of null (reading 'classList')

[faxunil]

Hi!

I couldn't exactly investigate when this problem is tiggered
in the error this is marked:
t.onblur=function(){V.value.focused.split(" ").forEach((function(t){A.value.classList.remove(t)}))},t.onfocus=function(){V.value.focused.split(" ").forEach((function(t){A.value.classList.add(t)}))}})),j.value=!0},q=function(){M.value.off(),M.value.destroy(),M.value=null},R=function(t,e){j.value=!1,q(),H()};return (0,vue__WEBPACK_IMPORTED_MODULE_0__.onMounted)(H

Im using this for a time slider, i convert the time to seconds.

Any Idea please?

Closing in absence of reproducible example.

1. Open the page and click on the handle
2. Click browser [back] button

This means the component is going to unload itself when one of the parts has active focus.
