HTML changes not reflect after reopening the illustrator extension.

I'm building extension for illustrator, i face issues in debugging. for javascript code, i use breakpoints for debugging in vscode using the extendscript extension. but, the problem is with the html code. when i open first time the extension in illustrator, it works fine, but as soon as i change the content of the html, it is not reflected on the extension even after reopening the extension in illustrator. when i reopen illustrator completely, it works fine. is their any kind of cache issues? can anyone please guide me?
