Stalled UI for 20 seconds when switching to Code View (Font Family Plugin)

[ebubekirtabak]

Expected Behavior:

Switching between Code View and Normal View in the Froala editor should be seamless and without any significant delays.

Actual Behavior:

When attempting to switch from Code View (HTML) back to Normal View, the entire page becomes unresponsive for approximately 20 seconds.

Steps to Reproduce:

We are using Froala editor with the following plugins: fontFamily, colors, fontSize, paragraphFormat, paragraphStyle, lists, align, emoticons, codeView, link, table, video, image.
The issue only occurs when the fontFamily plugin is included. Removing this plugin reduces the unresponsiveness to 5 seconds.

Editor Version

Froala editor v3.2.6, but the issue is reproducible even in latest version (jsFiddle)
