Style attribute not updating in Safari

I wonder if anyone has run into this. I've got a SplitPane component that I just discovered doesn't work in Safari. It turns out the

style

style

style

style attribute is not updating. I've got it down to

<div data-foo={`width: ${width()}`} style={`width: ${width()}`}>

<div data-foo={`width: ${width()}`} style={`width: ${width()}`}>

<div data-foo={`width: ${width()}`} style={`width: ${width()}`}>

<div data-foo={`width: ${width()}`} style={`width: ${width()}`}>

I can see

data-foo

data-foo

data-foo

data-foo changing in the element inspector, but

style

style

style

style remains unchanged.

It's the same with the object version of

style

style

style

style

<div data-foo={`width: ${width()}`} style={{width: width()}}}>

<div data-foo={`width: ${width()}`} style={{width: width()}}}>

<div data-foo={`width: ${width()}`} style={{width: width()}}}>

<div data-foo={`width: ${width()}`} style={{width: width()}}}>

Any ideas? Thanks : )
