Tick format attribute ignored after saving

[wgrusznis]

Describe the bug The tick format attribute is ignored after saving

To Reproduce Steps to reproduce the behavior:

1. Create a plot with a Categorical date on X axis
2. Apply Tick format for example {%b %y}
3. Press enter, and the preview should update with the correct Tick format
4. Click the Save button
5. X-axis Tick format goes back to default

Expected behavior The save button should not change attributes to default values.

Data category is not 'temporal':

we do want it to be categorical to be able to select a grid

with a 'temporal' category grid is no longer available as a layout

I found a workaround. If instead of saving project, you click on "back to report" and save it in the other prompt, the Tick format is applied correctly (does not go back to default value)

I would prefer to create just a formatted text column and sort it by the numerical column instead but sorting with Order by attribute is broken: https://github.com/microsoft/charticulator/issues/1052 :(
