По какой-то причине пробелы при включении отступа не были правильно обработаны при расчете размера строки.Замена функции measureLine
на следующую в codemirror.js
сделала свое дело:
function measureLine(cm, line) {
// First look in the cache
var cached = findCachedMeasurement(cm, line);
if (cached) return cached.measure;
// Failing that, recompute and store result in cache
var measure = measureLineInner(cm, line);
var origL;
var origR;
var lastR ="";
for (var mes in measure) {
origL = measure[mes].left;
origR = measure[mes].right;
if (lastR != "") {
measure[mes].left = lastR;
measure[mes].right = lastR + (origR - origL);
}
if (origL == origR) {
measure[mes].right = measure[mes].right + 8;
}
lastR = measure[mes].right;
}
var cache = cm.display.measureLineCache;
var memo = {
text: line.text,
width: cm.display.scroller.clientWidth,
markedSpans: line.markedSpans,
measure: measure,
classes: line.textClass + "|" + line.bgClass + "|" + line.wrapClass
};
if (cache.length == 16) cache[++cm.display.measureLineCachePos % 16] = memo;
else cache.push(memo);
return measure;
}
