[Bug] TextAlign extension adds "textAlign: null" to JSON output by default

Affected Packages

Version(s)

3.19.0

Bug Description

When using the TextAlign extension, every node of the specified types (e.g., paragraph, heading) gets a textAlign: null attribute in the JSON output, even if no alignment has been applied.

This behavior leads to bloated JSON data and can cause issues when synchronizing with databases or external systems that expect clean data structures. Ideally, the attribute should only be present if a non-default alignment is set.

Steps to reproduce:

• Install and configure @tiptap/extension-text-align with default settings.
• Create a simple paragraph without applying any alignment.
• Call editor.getJSON().
• Observe that the paragraph node contains "attrs": { "textAlign": null }

Expected Behavior

The textAlign attribute should be omitted from the attrs object if its value is the default (null or left), similar to how other extensions handle default attributes.

If null is the default here, shouldn't getJSON just omit textAlign unless it was explicitly set?
