/**
|
|
* Pre-open a browser tab inside a click handler, then point it at a URL once
|
|
* an async result arrives.
|
|
*
|
|
* Why: window.open() called after an `await` runs outside the click's
|
|
* transient user activation. Browsers expire that activation after ~5 seconds
|
|
* (Safari sooner), so popup blocking kicks in exactly when the request is
|
|
* slow: a cold serverless start made "Förhandsgranska PDF" silently do
|
|
* nothing (support: cbysea.se). Opening the tab synchronously keeps the
|
|
* trusted gesture; the tab is then navigated to the real URL, or closed again
|
|
* if the request fails. Same pattern as AGIPanel's signing tab.
