When pinned and width properties are set to igx-column, the column is not pinned.
"ID" column is not pinned. If removing width property, "ID" column is pinned.
"ID" column should be pinned.
@tkiryu This is by design. Check the console message.

@kdinev , I don't get it.
The width of "ID" column is only 100px. Whereas, the width of igx-grid is 100%.
I don't think the width of "ID" column can exceed the width of igx-grid. What's more, these configuration had worked until 7.1.1.
Could you reopen this issue and look into it again, please?
@tkiryu I thought this is reproducible only in the small stackblitz window. Now I see that you get this even if you open the app in full screen mode. Reopening and marking as regression!
@kdinev , thank you so much!
