Toolbar formatting buttons (Bold/Underline/etc.) do not reflect active formatting state

[Prthmsh7]

Currently, formatting buttons in the toolbar such as Bold, Italic, and Underline behave as momentary action buttons. When clicked, the formatting is applied, but the button immediately returns to its default visual state.

This creates a usability issue because the toolbar does not reflect the current formatting context of the cursor or selection.

Current Behavior

1. Clicking Bold applies bold formatting.
2. The Bold button does not remain visually selected.
3. When the cursor is placed inside already bold text, the Bold button does not indicate that bold formatting is active.
