1706218 - Give priority to name over id for usemap reference in image map

Status: NEW

(Core :: DOM: Core & HTML, defect, P3)

Description

[Karl Dubost💡 :karlcow]

Attachment: imagemap-id-test.html

1. Open the test case
2. Click on working and it goes to https://mozilla.org/
3. Back
4. Click on Not Working

Expected:
Goes to https://bugzilla.mozilla.org/

Actual:

• In Blink and WebKit, the Not working is going to https://bugzilla.mozilla.org/
• In Gecko, it is going to https://mozilla.org/

Gecko is using the id for deferencing the imagemap coordinates.
Blink/WebKit are using the name.

Not sure which one is right from the point of view of spec but just noticing it after a report on #webcompat on matrix.

Aha, Gecko just gives priority based on the order of the attributes.

Oh then we should be careful, maybe chrome is giving a similar priority but reversed? Need more tests with different orders.
