Bug: Data URL Truncation Risk in URL Handling
Removing the truncation of entry.url without handling data URLs could cause issues when the LCP element uses a data URL (e.g., data:image/png;base64,<very long base64 string>). Unlike globalhandlers.ts which has special handling for data URLs (lines 210-215), this code directly assigns the URL without any length protection. Data URLs with embedded base64 images can be extremely long (potentially megabytes), which could cause problems with attribute storage, transmission, or display in the Sentry UI.
