Deprecated selector in `polymorph-ui\index.less`

Automated report from the Atom deprecation cop

In polymorph-ui\index.less:

Starting from Atom v1.13.0, the contents of atom-text-editor elements are no longer encapsulated within a shadow DOM boundary. This means you should stop using :host and ::shadow pseudo-selectors, and prepend all your syntax selectors with syntax--. To prevent breakage with existing style sheets, Atom will automatically upgrade the following selectors:

• atom-text-editor[mini], atom-text-editor[mini]::shadow => atom-text-editor[mini], atom-text-editor[mini].editor

• atom-text-editor[mini] .cursor, atom-text-editor[mini]::shadow .cursor => atom-text-editor[mini] .cursor, atom-text-editor[mini].editor .cursor

• atom-text-editor .scroll-view, atom-text-editor::shadow .scroll-view, :host .scroll-view => atom-text-editor .scroll-view, atom-text-editor.editor .scroll-view, :host .scroll-view

• atom-text-editor .wrap-guide, atom-text-editor::shadow .wrap-guide, :host .wrap-guide => atom-text-editor .wrap-guide, atom-text-editor.editor .wrap-guide, :host .wrap-guide

• atom-text-editor .indent-guide, atom-text-editor::shadow .indent-guide, :host .indent-guide => atom-text-editor .indent-guide, atom-text-editor.editor .indent-guide, :host .indent-guide

• atom-text-editor .bracket-matcher .region, atom-text-editor::shadow .bracket-matcher .region, :host .bracket-matcher .region => atom-text-editor .bracket-matcher .region, atom-text-editor.editor .bracket-matcher .region, :host .bracket-matcher .region

• atom-text-editor .invisible-character, atom-text-editor::shadow .invisible-character, :host .invisible-character => atom-text-editor .invisible-character, atom-text-editor.editor .invisible-character, :host .invisible-character

• atom-text-editor .invisible, atom-text-editor::shadow .invisible, :host .invisible => atom-text-editor .invisible, atom-text-editor.editor .invisible, :host .invisible

• atom-text-editor .line.cursor-line, atom-text-editor::shadow .line.cursor-line, :host .line.cursor-line => atom-text-editor .line.cursor-line, atom-text-editor.editor .line.cursor-line, :host .line.cursor-line

• atom-text-editor .gutter .line-number, atom-text-editor::shadow .gutter .line-number, :host .gutter .line-number => atom-text-editor .gutter .line-number, atom-text-editor.editor .gutter .line-number, :host .gutter .line-number

• atom-text-editor .gutter .line-number.git-line-added, atom-text-editor::shadow .gutter .line-number.git-line-added, :host .gutter .line-number.git-line-added => atom-text-editor .gutter .line-number.git-line-added, atom-text-editor.editor .gutter .line-number.git-line-added, :host .gutter .line-number.git-line-added

• atom-text-editor .gutter .line-number.git-line-modified, atom-text-editor::shadow .gutter .line-number.git-line-modified, :host .gutter .line-number.git-line-modified => atom-text-editor .gutter .line-number.git-line-modified, atom-text-editor.editor .gutter .line-number.git-line-modified, :host .gutter .line-number.git-line-modified
