[pve-devel] [PATCH widget-toolkit 1/3] ui: logpanel: fix glitching on fast task logs

[Dominik Csapak]

when we follow (scrollToEnd === true) a task log that produces many lines
per second, we often get a 'total' back that exceeds our start+limit.

in that case we do not want to pad the bottom of the task log with empty
lines, we only want that for finished task logs to preserve the scroll
bar position+size.
