1484308 - Dragging the Size/Weight etc fields all the way to the right and holding down will continue to increase the value of the field

Status: RESOLVED INVALID

(DevTools :: Inspector, enhancement)

Description

[u554753]

Background:
Set the following values to true:
devtools.chrome.enabled = true
devtools.inspector.fonteditor.enabled = true

Steps to Reproduce:
1. Navigate to https://v-fonts.com
2. Navigate to "Merit Badge" font and click the link for "Info/fonts"
3. Navigate to "Developer Toolbar" CTRL+SHIFT+I
4. Using the tab key, navigate to the "Fonts" sub-section in the right window of the inspector.
5. Using the keyboard, change the values on the "Size" "Weight" and "Italic" fields and drag the indicator to a far right as it can go and continue to hold the left mouse key down.

Expected Results:
The indicator bar having an end to the right signifies that there would be a (default?) upper-limit of some sort. 

Actual Results:
There is no upper-limit and dragging the indicator to the right can continue to increase the value further and further.

This is actually a feature we introduced.  We wanted to allow the user to use the control even outside of the set limits, similar to what would be possible in CSS directly.

It seems like this behavior was confusing to you.  Could you explain your experience with it a little bit?

The auto-increment behaviour for the Size slider is intended as a result of Bug 1475208 which allows users to exceed the default constraints set on the font-size slider. 

For any other slider (aside from the upcoming line-height), this behaviour should not occur. I haven't been able to reproduce this. Italic, for example, is a toggle and can't be incremented.

Can you please re-validate with a latest Nightly build that *only* the Size slider auto-increments when dragging to the rightmost edge and holding there? The Size numeric input has the same behaviour when pressing and holding the Up arrow key.

Only Size slider + numeric input should auto-increment.

Apologies. Not sure why I listed Italic on there. Per Comment 1 and Comment 2 this seems like this is intended behavior. Closing this bug as INVALID.
