Correctly display widths specified in non-px units

[jesstelford]

Specifying a width with any unit other than px results in the following:

ie; it always appends px.

This change uses the assumption that when the width value ends in a number, it is an implicit px value, otherwise, it leaves it alone and uses the exact value supplied for display.

Hey mate, typescript isn't happy passing a number to the regex test function, just need to parse to a string before testing it

🤦 I couldn't replicate the failure locally and had no idea what was going wrong... Turns out I was still on the master branch 🤦

Thank you for the pointer. Should be fixed now 🤞
