[Bug]: Incorrect hex grid icons in Edit Map dialog

[kwvanderlinde]

Describe the Bug

When using the Rod Takehara icon theme, the Edit Map dialog shows pointy-top hexes where flat-top hexes should be and vice versa.

To Reproduce

1. Edit the current map
2. Select pointy-top (horizontal) hex option, and click "OK"
3. Turn on the grid and see flat-top (vertical) hexes on the map.

Expected Behaviour

Pointy-top hexes should have the pointy-top icon, and flat-top hexes should have the flat-top icon.

Screenshots

Additional Context

Comparing the above screenshots shows this is merely an issue of picking the wrong icon. Functionality is in other regards correct.
