[Bug?] VWindowItem is permanently disabled

[IVoyt]

I have VWindowItem components used in multiple places and everywhere the components have property disabled="false". Web browser interprets it as true even if it's value is false.

I didn't set it explicitly and I can't find any place where it is set so I make an assumption that it is default behaviour for the component which is totally incorrect and looks like a bug.

Did anyone face the same issue or maybe knows the solution?

<VRow>
  <VCol>
    <VTabs v-model="activeTab" dark next-icon="fas fa-angle-right" prev-icon="fas fa-angle-left" density="default" fixed-tabs>
      <VTab v-for="(tab, key) in tabs" :key="key" :value="key">
        {{ tab.title }}
      </VTab>
    </VTabs>
  </VCol>
 </VRow>

<VRow>
  <VCol cols="12" class="table-tab">
    <VWindow v-model="activeTab" style="width: 100%">
      <VWindowItem v-for="(tab, key) in tabs" :key="key" :value="key"> <!-- no "disabled" attribute -->
        <!-- content -->
      </VWindowItem>
    </VWindow>
  </VCol>
</VRow>

"disabled" was not set explicitly but it appears in generated html
