[bug] cmd+shift+click on OSC 8 hyperlink in terminal opens two tabs in the default browser #4168
Closed as duplicate
Description
Describe the bug
When cmd+shift+click on a hyperlink rendered via an OSC 8 escape sequence in the workspace terminal (e.g. emitted by Claude Code output), two tabs for the same URL open in the default browser.
This is reported for OSC 8 hyperlinks specifically; markdown-rendered links in chat have not been observed to exhibit this.
Steps to reproduce
- Open a workspace terminal in Superset.
- Run a command whose output emits an OSC 8 hyperlink (e.g. a Claude Code response that includes a clickable URL via OSC 8).
- Hold cmd+shift and click the hyperlink.
- Two tabs for the same URL open in the default browser.
Expected behavior
Exactly one tab opens.
Actual behavior
Two tabs open.
Environment
- Superset: 1.8.5 (latest stable)
- macOS
- Default browser: Arc

Adding configuration details and additional observations.
Settings (Settings → URL links)
Observed behavior
So with the current settings, ⌘ Click ("Open in browser") and ⌘⇧ Click ("Open in system browser") both end up in the system default browser (Arc). The duplication is specific to ⌘⇧ Click.
I have not investigated the source to confirm the cause; just reporting the observed behavior.
fix: solve #4168 — OSC 8 hyperlink click opens two browser tabs
