I initially reproduced the issue in the RTL Support example in the docs:
https://mui.com/x/react-date-pickers/adapters-locale/#rtl-support
Then I edited the code in CodeSandbox.

Steps:

1. Add a MobileDatePicker or regular DatePicker component to your app.
2. Add the appropriate properties in the theme and in the DatePickers SlotProps as explained in the docs:
   https://mui.com/x/react-date-pickers/adapters-locale/#rtl-support
3. To reproduce, click the 'Open In New Window' button in the sandbox preview:

3. Click the calendar icon on the MobileDatePicker - the picker pops open with the toolbar overlapping the calendar. 4. To reproduce with the regular DatePicker, click F12 to open the developer tools. Now click on the DatePicker's Calendar icon - also here, the toolbar overlaps the calendar.

Note:
Looking at the styles, it seemed that the issue was this property:

MuiPickersLayout-root .MuiPickersLayout-toolbar {
grid-column: 3;
}

When I unchecked the style - the layout fixed itself.

Current behavior

MuiPickersLayout-toolbar is overlapping the Calendar in RTL MobileDatePicker variant when the viewport is 833 pixels or greater:

Smaller than 833:

Greater than 833:

Expected behavior

The MuiPickersLayout-toolbar should appear side by side with the calendar, as it does when the DatePicker is not RTL:

Context

A responsive RTL DatePicker used with Hebrew that looks good across devices.

Your environment

npx @mui/envinfo
