[data grid] Bottom border doesn't reflect on pinned columns

[bojanmitic]

The problem in depth

I have set borders on row element. However, bottom border is missing on pinned columns. Please see attachments

As you can see green border(top border) goes all the way, even through pinned columns, but bottom(black border) goes only on unpinned columns. Why and how to fix it?

Your environment

`npx @mui/envinfo`

  Don't forget to mention which browser you used.
  Output from `npx @mui/envinfo` goes here.

Hey @bojanmitic ... it works for me: DEMO

Which version of the grid are you using?

[bojanmitic]

We are updating packages, so this happened with version 7.6.1. Earlier version was 6.18.6 and it worked as it should. Not sure why this happens. :(

Probably it's problem somewhere in our code

[michelengelen]

It might just be some kind of global styling ... If you could provide a reproduction I would be glad to assist.

Sure, thank you. I think we can close this issue.
