For the fun of it, when you save the following code blob as ~/.local/share/evolution/webkit-editor-plugins/com.example.CutQuotationLevel.js, then the next time you’ll reply to anything all the quotes for level higher than 2 will be automatically dropped. Play with the keepUpToLevel to find the accurate value for you.
Note of Evolution: Webkit editor plugin broken since 3.46.1 too.
I would attach the file, but this forum doesn’t let me attach .js files…
'use strict';
var comExampleCutQuotationLevel = {
name : "comExampleCutQuotationLevel.js",
setup : function(doc) {
if (doc.body) {
var keepUpToLevel = 2;
var selector = "blockquote[type=cite]";
while (keepUpToLevel > 0) {
keepUpToLevel--;
selector += " blockquote[type=cite]";
}
var elems = document.querySelectorAll(selector), ii;
for (ii = elems.length - 1; ii >= 0; ii--) {
elems[ii].remove();
}
}
}
};
EvoEditor.RegisterPlugin(comExampleCutQuotationLevel);
