On some websites that have untogglable CSS in the CSS inspector, clicking where a checkmark should be, crashes the web inspector. I attempted the same in Safari and Chrome. Either don't show checkmarks, and Safari does not crash, so it's probably something that is related only to Orion, or a different WebKit version.

Here is a video of how I can reproduce this every time, when inspecting the logo on bbc.com for example:

This is from a clean profile, the only thing that I did before was to click that I do not consent to advertising cookies so that the annoying large popup went away. So I am not using any extensions.

Expected behavior

Web inspector should not crash

Actual behavior

Web inspector crashes as described above and shown in the video.

There are other bug reports related to the web inspector, but they don't seem to be relevant to this particular sequence of events.

This is only relevant to the properties that don't have any checkboxes.

This is the mentioned exception in the dialog:

TypeError:​ null is not an object (evaluating 'this._styleSheetTextRange.collapseToEnd')​ (at CSSStyleDeclaration.js:​605:​45)​
_rangeAfterPropertyAtIndex @ CSSStyleDeclaration.js:​605:​45
