Exceptor widget in the logger UI doesn't work on HTML filters in the dev build #1861

Prerequisites

• I verified that this is not a filter issue (MUST be reported at filter issue tracker)
• This is not a support issue or a question
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
• The issue is not present after wholly disabling uBlock Origin ("uBO") in the browser
• I checked the documentation to understand that the issue I report is not a normal behavior

I tried to reproduce the issue when...

• uBO is the only extension
• uBO with default lists/settings
• using a new, unmodified browser profile

Description

As the title implies.

A specific URL where the issue occurs

https://www.naturalblaze.com/

Steps to Reproduce

filterAuthorMode must be set to true first.

• Browse to https://www.naturalblaze.com/ in a new tab and open the logger in another.
• Add www.naturalblaze.com##^#custom_html-7
  to my filters and refresh the page, then click on ##^#custom_html-7 filter to summon netFilteringDialog box and then click on the exceptor widget
• Notice filter doesn't get disabled(no strikethrough line over the filter), nothing happens.

Expected behavior

Filter gets disabled(strikethrough line over the filter)

Actual behavior

Filter doesn't get disabled(no strikethrough line over the filter)
