Safari Web Extensions: browser.webNavigation.getAllFrames by tabId return empty string url, when url is in blob protocol

Hello.

Environment

Safari version 18.1 (22B81).

Problem

In my Safari Web Extension i need to determine the url of the active tab.

I do it this way:

const onError = (error) => {
  console.error(error);
};

const getFrameUrl = async (frames) => {
  console.info(frames)
};

const getAllFrames = (frames) => {
  browser.webNavigation.getAllFrames({ tabId: frames[0].id }).then(getFrameUrl, onError);
};

browser.tabs.onUpdated.addListener(() => {
  browser.tabs.query({ currentWindow: true, active: true }).then(getAllFrames, onError);
});

The problem is that if the tab url is a link in the blob protocol, then the result function browser.webNavigation.getAllFrames({ tabId: tabs[0].id }) is as follows:

{frameId: 0, parentFrameId: -1, url: "", errorOccurred: false}

In Safari version 17 the correct URL value was returned:

{frameId: 0, parentFrameId: -1, url: "blob://<some id>", errorOccurred: false}

How can I fix the problem?
