https://bgrins.github.io/xbl-analysis/tree/#tree-base After <resources> has been removed, this binding is now only used to share a single one-liner method (_isAccelPressed). We can flatten inheritance by: 1) copy the line `aEvent.getModifierState("Accel")` to child bindings (https://searchfox.org/mozilla-central/rev/c9272ef398954288525e37196eada1e5a93d93bf/toolkit/content/widgets/tree.xml#22) 2) remove the tree-base binding 3) make anything that currently `extends="chrome://global/content/bindings/tree.xml#tree-base"` to `extends="chrome://global/content/bindings/general.xml#basecontrol"`
Try looks good.
