Description

  1. Tabs API events (e.g., onCreated, onUpdated) are not fired for tabs opened on the right side of a split screen.

  2. Tabs on the right side of the split are not returned when using:

  • chrome.tabs.getAllInWindow(_WINDOW_ID_HERE_, (tabs) => console.log(tabs))
  • chrome.tabs.query({}, (tabs) => console.log(tabs))
    This appears to be a duplicate of issue #104, but for some reason this issue still reproducible.

This behavior causes issues with extensions that rely on the Tabs API events. For example:

Tested on:

  • Browser: Microsoft Edge 135.0.3179.54 (Official build) (arm64)
  • Chromium version: 135.0.7049.42
  • OS: macOS 15.4 (24E248)
  • JavaScript engine: V8 13.5.21.5
  • User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/135.0.0.0 Safari/537.36 Edg/135.0.0.0
