Change the formatLog filter to limit the length of the value

[kovalewvladimir]

I suggest solving the issue described in #1968 as follows.
In the formatLog filter, add a check for the length of the string.If a large string is sent to convert.toHtml(String(value)), a RangeError exception will be thrown:

vue.runtime.esm.js:1897 RangeError: Maximum call stack size exceeded
