this issue can be fixed by using the pr in this repo, yes you have to build it by yourself

This is probably related to the issue I submitted as #20 and actually added a fix for this within Avalonia itself (since this project doesn't seem to get much attention anymore)

Excellent fix, thanks for this.

@charleypeng which PR are you referring to?

If you are hitting this, I solved it by replacing TabControl with TabStrip which does not detach anything from visual tree and does not prompt destruction of native elements (which lost browser state). Instead I just toggle visibility of the stuff in the main area based on the selected tab

Example:

<Grid RowDefinitions="Auto, *">
  <TabStrip>
    <TabStripItem x:Name="PayoutTab">
      <TextBlock Text="Payout" />
    </TabStripItem>
    <TabStripItem x:Name="SetupTab">
      <TextBlock Text="Setup" />
    </TabStripItem>
  </TabStrip>

  <WebView Grid.Row="1" Url="https://stripe.com"
           IsVisible="{Binding #PayoutTab.IsSelected}" />
  <TextBlock Grid.Row="1"
             IsVisible="{Binding #SetupTab.IsSelected}" >
    Some real setup here.
  </TextBlock>
</Grid>
