Duplicate Keys on X-Axis with Date Format and formatTick

When plotting a chart using Plotly with a small dataset and specifying the x-axis type as date, along with a custom formatTick function, the x-axis displays duplicate keys. This issue creates a confusing and cluttered appearance, as shown in the example provided below.

Steps to Reproduce:

Create a chart with the x-axis type set to date.
Use a small dataset with date values.
Specify a custom formatTick function for the x-axis.
Example:

You can see the issue in the following CodePen example:
CodePen Example

Expected Behavior:

The x-axis should display unique date values without any duplicates, even for small datasets, ensuring a clean and accurate representation of the data.

Actual Behavior:

The x-axis shows duplicate date values, leading to a misleading visualization.

Environment:

Plotly.js version: plotly.js-dist-min@2.32.0
Browser: chrome
Operating System: windows

This issue significantly impacts the readability of charts, especially when dealing with smaller datasets where clear and distinct x-axis labels are crucial.

Additional information:
by specifying type as category or explicitly specilfying tickvals and ticktext doesn't suit well for large dataset.
Screenshot

まず、リンクされている CodePen の例を Plotly.js 2.32.0 で実行し、カスタム formatTick 関数の有無による date-axis のラベルを比較します。ラベルの重複の原因となっている date-axis の tick 生成とフォーマット処理を追跡します。小規模な日付データセットで、category axes や明示的な tickvals と ticktext を必要とせずに、x-axis に一意で読みやすいラベルが表示されれば完了です。
