v23 doesn't replace multiple invalid {css.key} entries

[tivac]

Expected Behavior

If there's more than one {css.key} value that doesn't exist they should be replaced

Current Behavior

Only the first is replaced

Possible Solution

modular-css/packages/svelte/svelte.js

Line 48 in 0fc5403

new RegExp(`(${missed.map((ref) => escape(ref)).join("|")})`),

Needs to have the g flag set so it can match multiple times.

Steps to Reproduce (for bugs)

1. Create a template with multiple <div class="{css.key}" /> entries where key is different each time
2. Run it
3. Notice that only the first has been updated

Context

Trying to add new components and rough-in classnames still causes JS explosions
