Cannot enable Iconize in 2.14.7

[sicahjes]

Describe the bug

I can see that there was a fix in 2.14.6 for the 'Cannot Load' error, but I have updated to 1.14.7 and still cannot enable Iconize. When I try to enable, the error 'Failed to load plugin: obsidian-icon-folder' flashes up on the screen. The console error statement is:

Plugin failure: obsidian-icon-folder InvalidCharacterError: Failed to execute 'add' on 'DOMTokenList': The token provided ('highlightr-pen-general-/ quotes') contains HTML space characters, which are not valid in tokens.

I deleted the Highlightr plugin, just in case this indicated a conflict and not a reference to the Iconize code handling Highlightr, but the issue persists.

I have also disabled all the core bookmark plugin, as well as third party bookmark plugins.

To Reproduce
Avenue 1: Using Toggle

1. Go to 'Community Plugins'
2. Navigate to the 'Iconize' plugin
3. Toggle the plugin on to enable
4. See error.

Avenue 2: Using 'Enable' button

1. Go to 'Community Plugins'
2. Navigate to the 'Iconize' plugin
3. Click on the 'Iconize' text
4. Click on the 'Enable' button
5. See error.

Note: when I try this avenue, Iconize displays as enabled in Community Plugins. However, the app functionality is not available.

Expected behavior
Iconize to enable and functionality become available.
