[Data Grid] Page size does not reset after clearing a filter when using autoPageSize

[bahador-worklete]

When using autoPageSize with a DataGrid, if you set a filter and clear it, the page size does not reset.

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Let's say I have a DataGrid using autoPageSize with 100 rows, a page size of 20, and 5 pages. If I set a filter that returns 1 row, I will have 1 page with 1 row. If I clear that filter, I now have 100 pages with a page size of 1.

Expected Behavior 🤔

After clearing the filter, I would expect to have 5 pages of 20, just as I started out with when loading the DataGrid.

Steps to Reproduce 🕹

Steps:

1. Go to this link: https://material-ui.com/components/data-grid/pagination/#auto-size
2. Create a filter on the Trader Name field using any one of the populated values for that field
3. Notice that now there is only a single result and that the page size is 1
4. Clear the filter, and now you will see that the page size remains 1 but that you have 100 pages

Context 🔦

I just want the Data Grid to return to the same size it was when it loaded.

Can somebody test that it's the same root cause as #1334? Meaning that the fix we did cover this case too?

[dtassone]

Yes I checked it does cover it

[bahador-worklete]

I tested it on material-ui.com and it's broken there. I'm using 4.0.0-alpha.23 for my project and it's broken there.
Perhaps I'm doing something wrong?

Post Script: I searched for other issues but I guess I missed the one you linked. Forgive me if this is a duplicate. If so, I can move over there.

[dtassone]

It will be fixed in the next release.

[bahador-worklete]

Thank you.

[oliviertassinari]

Fix released in v4.0.0-alpha.25
