740772 - css style max-width/max-height on an embedded image destroys image proportions

Status: UNCONFIRMED

(Thunderbird :: Message Compose Window, defect)

Description

[V@no]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0
Build ID: 20120312181643

Steps to reproduce:

1) Compose an message.
2) insert an image through dropdown menu next to smiles menu
3) select a file (preferably large, 800x600)
4) click on advanced editor button 
5) in inline style tab add max-width 100px



Actual results:

Image will be resized to 100xNN (where NN is original height)



Expected results:

Image should be proportionally resized based on new width, at least that's how it works in Firefox.

max-width and max-height style attribute work as width and height in Thunderbird.

I am not an expert in HTML editing, but you can add "max-height" attribute as well. That will change the proportions.

Strange thing is, the attachment image view feature that resizes images to fit the screen uses max-width only and it shows images in proper proportions, but if the same attribute added to an in-body images (inserted into body of message, not attachments) distorts the proportions.
