Navigation mode: strange arrow key behaviour in nested blocks

[ellatrix]

Create a column block with a paragraph in one of the columns and leave the paragraph selected. Press Esc to enter navigation mode.

• Arrow up and down don't do anything.
• Arrow right doesn't do anything.
• Arrow left selects the column, which seems reasonable.

Now that the column is selected:

• Arrow down selects the next column... This is strange. I expect something downwards to be selected.
• Arrow right selects the paragraph inside the column. I expect the column to the right to be selected.
• Arrow up doesn't do anything.
• Arrow left selects the columns block, which again seems reasonable.

I would expect navigation mode to work more similarly like edit mode. Maybe we should reuse writing flow to also handle arrow navigation for navigation mode?

Cc @youknowriad since you know most about navigation mode. :)

I think the nested behavior was implemented as a v2 by @tellthemachines if I'm not wrong. For me at least, down and right should work the same and up and left as well because we shouldn't assume container orientation. and I expect like you to first go through the nested blocks before going to the next one.

[youknowriad]

Potentially we could leverage "orientation" config to be more precise but not sure if worth the complexity.

[ellatrix]

We don't need to look at container orientation if we just reuse the existing logic in writing flow. Instead of moving focus only the block selection would move.

Navigation mode has been removed.
