New Context recordHar with a relative path writes the HAR into the wrapper directory, also on the Robot Framework path #5152

A relative recordHar path is passed to the Node side verbatim and is resolved against the Node process's working directory — the wrapper directory inside the installed package. The HAR file is written there instead of under ${OUTPUTDIR}.

This affects ordinary Robot Framework runs, not only keywords called from Python. recordHar never passes through outputdir, so an absolute ${OUTPUTDIR} does not protect it.

Reproduce

*** Settings ***
Library    Browser

*** Test Cases ***
Record Har With A Relative Path
    New Browser    webkit    headless=True
    New Context    recordHar={"path": "relative_from_robot.har"}
    New Page       ${PAGE_URL}
    Get Title      ==    HAR lab
    Close Context
    Close Browser    ALL

Run with robot --outputdir out har.robot. Observed:

Browser/wrapper/relative_from_robot.har     1540 bytes   <- actual location
out/                                                     <- no .har anywhere
<cwd>/                                                   <- no .har

The test passes, so nothing signals that the file went somewhere unexpected. In a normal (non-editable) install this writes into site-packages.

Cause

recordHar is never touched on the Python side — it appears only in the keyword signature and documentation (Browser/keywords/playwright_state.py:607,649,752) and is forwarded to Node as given. The Node process runs with cwd=self._browser_wrapper_dir (Browser/playwright.py:280, passed to Popen at :104).

Compare recordVideo, which is resolved before being sent (Browser/keywords/playwright_state.py:948-960) and therefore behaves correctly.

Suggested fix

Resolve the recordHar path in _set_context_options the same way recordVideo's directory is resolved, so a relative path lands under outputdir.

Environment

Browser 20.3.0, Robot Framework 7.4.1, Python 3.14.7, macOS, webkit.
