Holdings editor times out with no warning

[Elaine Hardy]

The holdings editor times out with no warning. It will just stop responding and on redisplaying the tab at the browser, the error message Holdings editor timed out displays

This is in 3.8

The error message should include a link to get back to the record's holdings view.

The larger issue here is that timing out without warning the user or giving them the opportunity to extend their session violates WCAG 2.2.1: https://www.w3.org/TR/WCAG21/#timing-adjustable This is a pretty severe problem for assistive technology users.

See also bug 1894900 on timing out in the OPAC.

We can do any or all of the following to resolve the problem:

1. Add a timeout warning dialog, as in this example: https://accessibility.huit.harvard.edu/give-users-control-over-timeouts

2. Reset the time based on virtually any browser event (scroll, focus, change, blur, any keyboard or pointer event)

3. Clearly state the timeout duration
