NOTE: should be implemented after {T318815}
Currently the setting to hide frame is only accessible in wikitext and cannot be set in VE. We will add a toggle to show/hide frame for maps in Visual Editor (see mock) to the "Map options" tab.
== Requirements
[] Add `ToggleSwitchWidget` beneath the position setting with label `Show frame`
[] Change section label to `Display`
[] The setting should be turned on by default
[] If there is a caption, then the toggle should be disabled in the on position
[] If the map is set to frameless, but a user adds a caption, the toggle should be switched to on and disabled
[] If a caption is deleted, then the toggle should be un-disabled
[] As the options tab gets longer, when the user scrolls down, the whole dialog scrolls (existing behavior)
[] Add text to `Display` info icon help text (added in T318818 ): `Turning off the frame causes the embedded map to be drawn without a frame (border), similar to frameless images. This option is disabled if the map has a caption.`

==Technical implementation
Similar to the position attribute, this can be added to the mapframe:
```
<mapframe frameless>
```
