Table of Contents Links are Case Sensitive

[ndbeals]

Current behavior

Currently, when using a table of Contents (auto generated in another tool, as Boostnote doesn't have this feature yet), the links to the headings must be capitalized the same as the headings themselves are.

Expected behavior

When I click on a TOC heading, it'll jump me to the correct heading.

Steps to reproduce

1. Copy + paste the following markdown into a note

    - [Heading 1](#heading-1)
    - [Heading 2](#heading-2)
        - [Heading 3](#Heading-3)

# Test Note

## Heading 1

## Heading 2

### Heading 3

2. Attempt to navigate with the Table of Contents in the Preview window.

Environment

• Version : Boostnote 0.11.5
• OS Version and name : Windows 7 Enterprise

DOM IDs are generally case-sensitive, as are URLs. The HTML 4 spec states they were case-sensitive but that's no longer the case in the HTML 5 spec.

In Chrome, if you go to a URL that has an anchor link, and change the case, it'll no longer work so that's the same behavior Boostnote displays.

Yeah, well a bunch of other markdown table of contents generators (and programs that follow TOC's properly) are case insensitive. Pandoc, typora, markdown-it-toc, etc, etc, etc.

I don't think it's all of them that're wrong and Boostnote is the only one that got it right. Also, the Common Mark Spec defines label (and link label) matching as case-insensitive.

As the program is built in Electron (and thus wrapped around Chromium), the preview is rendered based on the HTML5 spec. It's not so much that the other content generators are case insensitive so much as it is they automatically convert the link fragments to lowercase.

We now have TOC generator to take care of this: #2281

I also want to add that if the heading has any part in Italics then also it does not work.
