Considering limiting hover length

TypeScript Version: 3.7.x-dev.201xxxxx

Search Terms: hover, length

Code

// A *self-contained* demonstration of the problem follows...
// Test this by running `tsc` on the command-line, rather than through another build tool such as Gulp, Webpack, etc.

Expected behavior: JSDocs can always be shown

Actual behavior: JSDocs is hidden because hover is too long

It seems certain type hover will be formatted to one property each line. I'm wondering if you could only adopt this behavior when the total lines do not exceed a threshold (like 10 lines), so it wouldn't affect JSDocs.

提供された Playground Link を使ってまず hover の動作を再現し、リンクされている VS Code issue も含めて、期待される表示と実際の表示を比較します。hover のフォーマット動作を調査し、短い type hover を変更せずに JSDoc の可視性を維持するために、行数のしきい値をどのように設定できるかを判断します。長い hover でも JSDoc が引き続き表示され、短い hover では提案されたフォーマットが維持されれば完了です。
