diag_logs.php - Line wrapping issues with long unbroken lines
Looks like if there is a log line long enough it causes the timestamp column to wrap, too, which negatively impacts the formatting for many more lines than it should.
Can that one column be set not to wrap?
Also in that case it the line is still causing a horizontal scroll bar since it's all run together and not breaking properly it never wraps. (See #5395 for more discussion on that)
