According to the ECMA-262 spec (page 473 Note 4): "Finite numbers are stringified as if by calling ToString(number). NaN and Infinity regardless of sign are represented as the String null." There isn't a need for serializing NaN at the moment. TimelineRuler however, needs to serialize Infinity in order to persist the "nothing is selected" ruler selection state, which is represented by a selection interval of [0, Infinity). *NOTES This can be added by augmenting JSON.stringify in Utilities.js, or by adding a special case in WebInspector.Setting. 1167570 1 webkit-bug-importer 2016-02-23 15:42:22 -0800 <rdar://problem/24802960> 1167571 2 timothy 2016-02-23 15:47:55 -0800 We could also store that "entire range selected" state as a bool and restore [0, Infinity] on load from settings. 1167573 3 mattbaker 2016-02-23 15:50:23 -0800 (In reply to comment #2) > We could also store that "entire range selected" state as a bool and restore > [0, Infinity] on load from settings. That is a possible solution. I'll try this, as well as MAX_VALUE as an alternative to Infinity in TimelineRuler code go with the cleaner solution. 1167989 4 mattbaker 2016-02-24 17:41:21 -0800 Using Number.MAX_VALUE instead of Infinity solved the issue.
