replace plugin. default "delimiters" value is breaking for developers #905

• Rollup Plugin Name: @rollup/plugin-replace
• Rollup Plugin Version: 2.4.2 (currently latest)
• Rollup Version: 2.50.6
• Operating System (or Browser): macos (but it's irrelevant in this case)
• Node Version: 16 (but it's irrelevant in this case)
• Link to reproduction: a PR fix(replace)!: issues with nested objects replacements #903

Actual Behavior

Currently, developers have issues with replacements w/ nested access.
If you attempt to replace typeof window with "object", you would see the following scenarios:

• typeof window will be replaced
• typeof window.document will be replaced, resulting in "object".document (which is an error)
• typeof windowSmth will not be replaced due to a \b boundary

Expected Behavior

• typeof window.document will NOT be replaced, resulting in "object".document (which is an error)
