Prisma Studio: Select row and select all rows are missing checkboxes

[kevenleone]

Bug description

I found the following issues with the latest version of Prisma Studio

In the first column of the row and in the header it's missing the checkbox
The behavior of selecting multiple rows is not working, as the selected rows are overwritten by the last checked

Cross posting issue: prisma/studio#1504
Cross posting fix: prisma/studio#1505

Severity

🔹 Minor: Unexpected behavior, but does not block development

Reproduction

1. Open Prisma Studio
2. Try to Select a Row on the first column (Checkbox is not listed)
3. Try to Select multiple rows (Clicking one by one)
