Issue Details

I'm trying to display a pdf inside a webview which has its own partition. The PDF plugin is loading (visually I can see the gray PDF background), but no pdf content is displayed. I'm using this code

<webview plugins="true" partition="ramdomid" src="https://arxiv.org/ftp/arxiv/papers/1703/1703.09735.pdf"></webview>

When I'm using the same code without the partition attribute, everything is working.

• Electron Version:
  • 11.1.1
• Operating System:
  • Windows 10 2004
• Last Known Working Electron version:
  • ?

Expected Behavior

I should be able to see the pdf content in a webview with a partition set

Actual Behavior

The webview is displaying the pdf plugin surface without the pdf content

To Reproduce

Working html code

<webview plugins="true" src="https://arxiv.org/ftp/arxiv/papers/1703/1703.09735.pdf"></webview>

Non working html code

<webview plugins="true" partition="ramdomid" src="https://arxiv.org/ftp/arxiv/papers/1703/1703.09735.pdf"></webview>

Workaround

You can fix this by making partition persistent (add persist: before the partition name)

<webview 
  partition="persist:partitionName" 
  src="file:///C:/test.pdf"
></webview>

let window = new BrowserWindow({
  ...
  partition: "persist:partitionName"
})

You can fix this by making partition persistent (add persist: before the partition name)

Not a fix but an ugly workaround. There are cases when persist:-prefixed partition is defined by design, ie in-memory/temporary web storage use case.

@codebytere can you also add 15-x-y and platform/linux labels?

Btw, blob url created via URL.createObjectURL and applied to webview is also the case.

there are been tree years now this bug is revealed. I guess the project should focus on what happen, because it is an important feature lots of others project depend on. Thanks for you continuous support.
