Description (last modified by )
When using Chrome, in Admin's change list page, the actions selection counter (e.g. "99 of 100 selected") will be reset/get out of sync if the user leaves the page and then returns via the browser's back button but the rows will continue selected.
Steps to reproduce:
- Open the admin's change list page
- Select some rows, e.g. 10 rows
- The selection counter text will display "99 of X selected"
- Click on any link to navigate to another page
- Click the browser's back button
- The 10 rows will continue selected
What happens:
- The selection counter text will wrongly display "0 of X selected"
What should happen:
- The selection counter text should display "10 of X selected"
Tested on MacOS Google Chrome Version 113.0.5672.12

Row selections are preserved when using browser's "Back" in Chrome only. As far as I'm aware, this is not an intended feature
Is not intended, but that is how Chrome works and if I'm not wrong we decided no reset the checkboxes status (https://github.com/django/django/pull/15938#issuecomment-1214660476)
I remember I did a fix after go back to preserve the highlighting of the rows: https://code.djangoproject.com/ticket/33491.
We should force the counter sync.
Cauê Thenório, do you want to work in a patch?

I did a test here with different browsers on MacOS:
- Chrome 113 keeps rows selected and the counter is reset ❌
- Safari 16.5 keeps rows selected and the counter is updated ✅
- Firefox 115 clear selection and the counter is updated ✅
Each browser has a different behavior but only Chrome gets the counter out of sync.
Based on this discussion: https://github.com/django/django/pull/15938, it looks like it was decided to keep Chrome's behavior as users may get used to this behavior when using Chrome, and it saves user's work compared with Firefox, where the user will need to reselect previously selected rows.
Yes Marcelo Galigniana, I would like to work on a patch. I believe it will be a couple of the lines, to call the updateCounter function when the page loads.

After some tests, I found out that Chrome restores the selection after Actions(actionsEls) is executed, therefore calling updateCounter in the body of Actions function won't work as Chrome didn't restore the selection at that point.
In this comment: https://bugs.chromium.org/p/chromium/issues/detail?id=1057463#c5
A Chrome developer states the values are restored before the pageshow event: https://developer.mozilla.org/en-US/docs/Web/API/Window/pageshow_event
I'll write a patch to run updateCounter when the pageshow event is triggered.

Thanks for the report. Row selections are preserved when using browser's "Back" in Chrome only. As far as I'm aware, this is not an intended feature, however we should keep the counter in sync or uncheck the rows.
