Tabview: Forward Button Visible with Fractions

[denny99]

Describe the bug

For checking if the forward button needs to be displayed, it compares the current scrollstate with the actual width of the content.

The issue is that the scrollWidth is rounded and the scrollLeft Value is not.

In my case the scroll width actually is: 1671.5, but during runtime the value reads 1672. Where as the scroll left value is and stays 150.5.

Expected behavior

updateButtonState(this: TabView): void { const content = this.content!.nativeElement; const {scrollLeft, scrollWidth} = content; const width = DomHandler.getWidth(content); this.backwardIsDisabled = scrollLeft === 0; this.forwardIsDisabled = Math.round(scrollLeft) === scrollWidth - width; }

I could create a PR with the rounded scrollLeft, so it actually matches the rounded scrollWidth

Mentioning the scrollLeft decimal value:
