Tanstack start VSCode debugging

Start

Describe the bug

Hi All
I really like Tanstack Start but at the moment I don't see a path to migrating to is because the debugging just doesnt work. If I have a root component called index.tsx, I can hit a breakpoint within a server function for the first time but then subsequent breakpoints don't work. Also, when I hit a breakpoint I don't see the value of the variables, it just shows their type. Then when I continue it goes into another file called index.tsx?tsr-split which looks like transpiled code.Is this possibly because of Vinxi? Is this a known problem and do you think it will be resolved.

Thanks for all the hard work

Steps to Reproduce the Bug or Issue

open in vscode
run the vscode Debug server side from debug tab
run the vscode Debug client side from debug tab
put a breakpoint in index.tsx at line 24
refresh the page
hover over the count variable and it will just show "const count: number"
press F5
you will be taken into a file called index?tsr-split
If you click the button in the web page it should break on the breakpoint again but doesnt.

Expected behavior

I expect to see the actual count value and also be able to hit the breakpoint each time
