Preserve spaces and incorrect behavior on trailing wsp

<text x="200" y="230">
		<tspan text-decoration="underline" xml:space="preserve"> space test</tspan>
		<tspan text-decoration="underline" x="200" y="250">space </tspan>
		<tspan text-decoration="underline" xml:space="preserve" x="200" y="270">space </tspan>
	</text>

The trailing space on each span is incorrectly added as leading space to the next span on xml:space=preserve.

Filed issue for Blink as well. Both, WebKit and Blink share the same code still: https://code.google.com/p/chromium/issues/detail?id=537581

It affects the last character regardless of whether it's a white space.

        <text x="200" y="230">
                <tspan text-decoration="underline" xml:space="preserve"> space test</tspan>
                <tspan x="200" y="250" xml:space="preserve">space</tspan>
                <tspan text-decoration="underline" xml:space="preserve" x="200" y="270">space </tspan>
        </text>


        <text x="200" y="230">
                <tspan xml:space="preserve">ƒ</tspan>
                <tspan xml:space="preserve">(x)=2e</tspan>
                <tspan xml:space="preserve" dy="-10">-2x</tspan>
        </text>

I am able to reproduce this bug in Safari Technology Preview 154 and the last line has leading space while both Chrome Canary 108 and Firefox Nightly 108 does not.

It was fixed by following Blink commit:

https://chromium.googlesource.com/chromium/src.git/+/9331211c22aee7b499131aa1c58ce515deceeb45

We do have references to following code here:

Just wanted to updated latest result. Thanks!
