html - Height of textarea does not match the rows in Firefox

Question

The textarea's rows attribute does not match the number of lines in Firefox. For instance:

<textarea rows=4 cols=40>
1
2
3
4
this line is visible in FF
</textarea>

Example: http://jsfiddle.net/Z7zXs/6/

How can I fix this issue? The textarea should only display 4 lines (instead of 5) for rows=4.

There are lot of answers but wasn't suitable for me:

• CSS rule (height: 5em;) is not flexible enoutgh because it completely overrides rows attribute
• And I don'n want to use JavaScript

There is a "bug": TEXTAREA incorrectly applying ROWS= and COLS=

So here is my solution:

FF adds height to the TextArea to reserve place for scroll-bars.

I don't need horizontal scroll bar so it helps with fixing the issue: following css rule can be added to textarea:

overflow-x: hidden;

Here is example. It works even with rows=1.
