[arthurtsenin]

Description:
When applying hyperlinks to formatted text in EditorJS, all existing HTML tags (<b>, <i>, <font>, etc.) are removed, leaving only plain text wrapped in an <a> tag.

Current Behavior:
Format text with any combination of formatting (bold, italic, color, etc.)

Example: <b><font color="red">Text</font></b>

Apply hyperlink

Result: <a href="#">Text</a> (all formatting tags are lost)

Expected Behavior:
Hyperlinks should wrap existing formatting without modification:
Expected result: <a href="#"><b><font color="red">Text</font></b></a>

Reproduction Steps:
Create formatted text in EditorJS
Select the formatted text
Use the hyperlink tool
