Number fields: weird keyboard behaviour and values don't save

Steps to reproduce

1. Create a table with a number field with 2 decimal places, no maximum and mandatory. Bug appears to be triggered by maximum field being blank.
2. Click Create row. When you type into the number field, the first digit is always 0 regardless of the number typed.
3. Click Save. The resulting row has no value in the number field.
4. Editing a row with data and saving it looses the data.

Expected behavior

Number value should be stored as typed.

Actual behavior

Number fields are always blank, and the input field always shows 0 for the first digit.

Additional info

In my test, the row also had a link to a contact. When creating the row, the contact is saved. If I edit the row, make no changes, and click save, the contact is also lost.

Reproduce the issue in the Tables app using a mandatory number field with two decimal places and a blank maximum, then trace the number-field create/edit and row-save entry points. Check the Firefox behavior and the linked-contact case; done means typed number values and existing linked data survive creation and unchanged edits.
