            Bug ID: 225962
           Summary: Calculated width percent loses the floating point and
                    cause line wrap
           Product: WebKit
           Version: Safari 14
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

Steps to reproduce:
1. Open https://jsfiddle.net/jxd3c08u/2/

What went wrong:
Second and third "Hello World" wraps into new line after "Hello"

Expected result:
"Hello World" should be in one line


Cause:
The container element of the Hello World text has floating point width: 183.03px. When we use calculated width (calc(100% - 0px)) it cause probably a rounding and the width for that element becomes 183px and the two word no longer fit into that. 


Firefox and Chrome behaves as expected and there is no line wrap.
