2008366 - Reloading about:blank causes remote type change

Status: NEW

See comment 49.

When reloading the inner iframe of <iframe src="data:text/html,<iframe></iframe>"></iframe>, this can lead to a remote type change if the top document has a different remote type than the outer frame. The following already reproduced before bug 543435.

STR

• Open the test case as a file:// URI
• Open the devtools console
• Go to the data:text/html, execution context
  • frames[0] should not be restricted
  • Reload the outer frame window.location.reload()
• Again, go to the data:text/html, execution context
  • Check frames[0]

Expectation

• The outer frame can still access the inner frame after reload

Actual

• The outer frame is restricted from accessing the inner frame after reload, indicating a remote type change
