Hi Pham Van Sy,
The issue you are facing is due to a styling conflict. To resolve this, you need to add the following CSS properties to the <body> inside the <style> tag in your HTML file:
body {
-webkit-user-select: none;
user-select: none;
}
This will prevent unintended user selection and help resolve the issue.
If the issue still persists, please update us and share your sample along with the steps to replicate the issue.
Let us know if you need any further assistance.
Best regards,
Pranoove
