Describe the bug / error

When "inlineEditField" JSON property is applied to a DateTime column, the related date picker appears on the upper-left corner of Microsoft Lists user interface:

Furthermore, the placeholder letters related to week days are displayed based on a wrong language. For example, here is what's happening with italian UI:

Just for curiosity, I had a look at what's going on behind the scenes and here is the result in my browser DOM:

This bug has been confirmed by @tecchan1107 too.

Steps to reproduce

1. Create a new list
2. Add a date-time column named "Start" (just as an example)
3. Click on Column setting --> Click on Format this column --> Click on Advanced mode
4. Apply the following basic JSON code and save:

{ "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json", "elmType": "div", "inlineEditField": "[$Start]", "style": { "box-sizing": "border-box", "padding": "0 2px", "overflow": "hidden", "text-overflow": "ellipsis" }, "attributes": { "class": "sp-field-fontSizeMedium sp-css-color-BlackText sp-field-bold" }, "txtContent": "[$Start.displayValue]" }

Expected behavior

When clicking on a cell to trigger the inlineEditField property, the date picker should appear positioned exactly over its underlying cell.
