I will happily review any CLs to fix this but I'm tempted to close this issue given the low priority of the internals page.

What do you think of marking it as a Hotlist=GoodFirstBug instead of closing it?

In bluetooth-internals page, most of screens uses object_fieldset.js for showing the properties.
So if we modify the redraw function by adding a check for value and proceed for drawing, it will take care of hiding the false properties in all the screens. Is this change Ok or should be handled specifically for characteristics properties only?

OK to change all rendering using the component.  However, the usefulness of having a shorter list of only non-false items comes with a trade off of not seeing what the other potential items are.

To explain, a novice, or even experienced Bluetooth developer may look at the UI and not know that certain property types exist.  Currently the UI hints to them that these exist and are false, perhaps leading them to adjust their peripheral device to change behavior to work correctly.  If we remove them all then developers won't notice.

I wonder if we can render all items but hint succinctly that there are more.  Or, have a toggle that the user can press to show all items.

E.g. some snippet of JavaScript on a button that toggles a CSS property to show hidden items, or to show a <dialog> with all items included.

Having a toogle would be great indeed to show all items!
