Cannot use "u" as an alias name in ER Diagram

[danivideda]

Description

When using "u" as an alias in ER Diagram, it gives me an error.

erDiagram
  u[User] {
  string name
}

When this issue is fixed, this should render correctly on GitHub markdown too:

erDiagram
  u[User] {
  string name
}

Loading

Steps to reproduce

1. Open any mermaid supported editor (I use Obsidian, but the error could be seen on Github's markdown too)
2. Copy this code

erDiagram
  u[User] {
  string name
}

3. It will give error as shown in the screenshot below.
4. If you change the alias other than "u" (i.e "p", "q", "us", "ub", etc.), it will work as intended without any errors
