Marker view must escape mnemonics in description column tooltips

[Bananeweizen]

I recently refactored some generics related code and noticed that problem markers containing text like List<Foo & Bar> miss the & in their tooltip. The same can be more easily reproduced by creating a bookmark in the bookmark view with the title A & B. It's tooltip also misses the &. Looks like this on Windows:

I tried calling escapeMnemonics on the method of the MarkerColumnLabelProvider.getToolTipText() to fix this, but I only managed to provide an addition non-native tooltip with correct text. The native tooltip remained wrong, and I'm unfortunately lost in those native tooltips.

I am not sure how to reproduce this issue or which tooltip is mentionned by the issue. Both a problem with a generic containing an "&" and a bookmark containing "&" work fine.

1) Bookmark "A & B"

(1.1 in the bookmark view)

(1.2 as editor tooltip)

2) An example with generics https://gist.github.com/Wittmaxi/83446e69b04d8d58bbf53b1cd65f8476

(2.1 in the problems view)

(2.2 as editor tooltip)

Note,

that the MarkerColumnLabelProvider's getToolTipText is implemented here and set to return null.

	@Override
	public String getToolTipText(Object element) {
		return null;
	}

I was able to reproduce this bug just now. The tooltips are only shown when the column is not wide enough to fit the entire text inot it.

I will work on reproducing this in a minimal example and possibly fixing this issue

It looks like this is not broken in the ProblemsView but in SWT's TreeColumn
Using TreeColumn's, I can reproduce this bug

(code here)

A simple Tree will not exhibit this behaviour, correctly rendering the &

Neither will a Table
