Ctrl+click does not open links in left/right split panes (works when pane is zoomed)

[Blue-B]

Is this a reproducible bug?

• I confirm this is a reproducible bug, not a feature request, idea, question, contribution proposal, or direction check.
• I reproduced this bug on the version and environment reported below using the exact steps provided.

Current behavior

Ctrl+Left Click on a link inside a pane does not open the URL when the pane is part of a left/right split layout. The same link opens correctly when the pane is zoomed to fullscreen or is the only pane in the tab.

Expected behavior

Ctrl+Left Click should open the link regardless of the pane's position in a split layout.

Reproduction

1. Run herdr in a terminal.
2. Open a pane running pi (a TUI agent that prints OSC-8 hyperlinks, e.g. a https://github.com/... link in a reply).
3. Split the tab side-by-side: herdr pane split --direction right.
4. Ctrl+click the link in that pane. Nothing happens, no browser tab opens.
5. Run herdr pane zoom on the same pane, then Ctrl+click the same link. It opens correctly.
6. Zoom back out. Ctrl+click fails again.

Impact

Split layouts are the default way to run multiple agents side by side. Links in agent replies are unusable by mouse in that layout, forcing copy-paste of URLs. Any pane printing OSC-8 hyperlinks is affected.

Environment

• Herdr version: 0.7.4 stable (reproduction time); upgraded to 0.8.0-preview after, not yet retested
• Update channel: stable at reproduction time
• Operating system: Linux (WSL2, Ubuntu 24.04)
• Terminal: Windows Terminal
• Shell, if relevant: bash
• Relevant config, if any: default config.toml
